Two official versions with different histories
“Ariana Grande feat. Taro Hakase Baby I” refers to an authorized Japanese reworking of Grande’s 2013 single “Baby I.” It is not the original single master, despite using Grande’s existing vocal, and it is not an unofficial remix. Japanese violinist Taro Hakase added a prominent new violin part and altered the recording’s instrumental profile for a market-specific release.
The original “Baby I” arrived in the United States on July 22, 2013, as the second single from Grande’s debut album, Yours Truly. The Hakase version belongs to the following year. Universal Music Japan announced that it would appear as a Japanese bonus track on Grande’s second album, My Everything, released there on August 27, 2014.
Catalog dates can make the chronology look less tidy. Spotify identifies a Japanese “Baby I” package featuring Hakase with an August 6, 2014 date, while an August 18 label press release said Japanese customers pre-ordering My Everything could download the track immediately. Universal later announced a separate mobile-download release on September 10. Those are different digital-product stages, not evidence of a leak or multiple mysterious recordings.
August 27 remains the clearest defining date: it was when the version became a documented bonus track on the commercially released Japanese album. The Japanese CD’s catalog number, UICU-1255, and release date are independently recorded in the VGMdb album entry, which also credits Hakase as guest violinist.
The song Grande recorded in 2013
Before Hakase entered the story, “Baby I” was an exuberant retro-R&B showcase designed by experienced specialists. Kenneth “Babyface” Edmonds, Antonio Dixon and Patrick “J. Que” Smith wrote the song; Babyface and Dixon produced the original recording. Grande is the lead vocalist but is not a credited songwriter.
The original arrangement combines syncopated drums, handclaps, brass accents and tightly stacked backing vocals. Its lineage lies in late-1980s and 1990s R&B-pop, with a touch of 1970s disco brightness. Grande’s task is technically demanding: the melody packs quick turns and dense runs into a tempo that leaves little room to breathe.
Reports that the composition was initially intended for Beyoncé are longstanding, but that origin should not be confused with the later Japanese collaboration. Grande discussed the song and Babyface’s involvement in a 2013 Complex cover interview. Whatever its earliest destination, the released 2013 performance was Grande’s, and the Hakase edition was subsequently built from that established recording.
“Baby I” helped define Grande before her full pivot into global EDM-pop. Its original video, released during the Yours Truly campaign, styled her as a bright, street-level 1990s revivalist. The Fader described the clip as a deliberate-looking memory of Nickelodeon-era pop in its contemporary review. The Hakase version does not replace that single or its video; it localizes the song for a new context.
What Taro Hakase changed
Hakase’s violin is not a short ornamental solo appended to the ending. It threads through much of the arrangement, answering Grande’s phrases, reinforcing transitions and pushing into the spaces between vocal lines. The familiar rhythm track and vocal remain recognizable, but the violin supplies a second melodic protagonist.
Universal’s press material provides the most precise official description. The label said Grande had accepted an invitation connected to GO-GO Tamagotchi! and that Hakase’s violin was added to the hit single for the new version. The announcement explicitly credits Grande for vocals and Hakase for violin, while retaining Babyface, Dixon and Smith as the writers.
That distinction resolves the misleading “CDQ” language that accompanied some historical posts. “CDQ” was internet shorthand for supposed compact-disc quality, not an official subtitle. Once the Japanese edition of My Everything was released, there was no reason to treat the track as an unreleased file. It was a licensed Republic/Universal recording with a physical catalog placement and later authorized digital distribution.
Musically, the new violin changes the center of gravity. The original production’s brass and percussion suggest an American R&B revue; Hakase’s sustained lines add crossover-pop sweep. His instrument sometimes shadows Grande’s agility and sometimes counters it with longer arcs. The contrast makes the vocal sound even more percussive.
That is interpretation rather than a separate production credit. The documented credit is guest violinist. Publicly available sources do not establish that Hakase rewrote the composition, and he is not listed as an additional songwriter.
Why Japan received this version
The collaboration was tied directly to Grande’s unusually strong early relationship with the Japanese market. Universal’s announcement explained that she was an enthusiastic Tamagotchi fan and had visited the brand’s Harajuku store during her first trip to Japan. The production team behind the television anime then approached her about using the song.
The Hakase version became an ending theme for the TV Tokyo anime GO-GO Tamagotchi! beginning in October 2014. The label characterized it as the first use of a Western-language pop song across the anime franchise’s six-year television history at that point. The placement was therefore not a fan-made synchronization or a later video edit; it was part of the version’s original commercial purpose.
Apple Music’s profile of Taro Hakase likewise identifies his 2014 Grande collaboration and its use as the anime’s closing theme. Hakase was already a prominent crossover violinist, composer and label founder in Japan, making him a logical bridge between imported American pop and local mainstream programming.
The Japanese edition was not merely a storage place for an orphan remix. My Everything was a major campaign in the country, and its market-specific eighteenth track gave local buyers something unavailable on the standard international sequence. The album’s Japanese Apple Music edition still lists 18 tracks, preserving the structure of that expanded release.
The collaboration moved onto the stage
The two musicians eventually performed the arrangement together. During Grande’s August 2015 Tokyo concert, Hakase appeared as a surprise guest for the first live performance of their version. Universal Music Japan’s concert report explicitly calls it the Japanese bonus track from My Everything and describes Hakase’s entrance during “Baby I.”
That performance confirms that the feature was more than a metadata convention. Even though the studio release reused the core of Grande’s earlier recording, the partnership became an actual live exchange between singer and violinist.
A rights-holder upload now makes the studio version straightforward to identify: Grande’s official artist channel carries “Baby I (Official Audio) ft. Taro Hakase”. Its later upload date should not be mistaken for a new release date. Catalog owners frequently add older masters to YouTube years after their original issue.
The version’s proper place in the catalog
The simplest accurate description is “the official Taro Hakase version of Ariana Grande’s ‘Baby I,’ released for Japan.” It originated during the My Everything era, used Grande’s established 2013 vocal and songwriting, featured newly added Hakase violin, and served a documented anime tie-in.
It was neither a leak nor a newly composed sequel, and it should not be folded silently into the history of the original 2013 single. The two masters share a foundation but had distinct release functions: one introduced Grande’s debut-album sound internationally; the other translated that sound into a specifically Japanese crossover event. Hakase did not simply decorate the record. His violin supplied the element that allowed an already familiar hit to acquire a second cultural life.
