Having previously achieved success in the American market first with their single "Back Here", "Still on Your Side" was BBMak's second top 10 hit in the UK.

[5] The song is written by Bridget Benenate, Bob Thiele Jr., and Dillon O'Brian, in addition to the three members of BBMak.

[1] Billboard wrote the song is “a joyful all-out anthem” and “has a lyric to connect with the masses, the hooks to again reel in BBMak’s younger fans, and the elegance and credible instrumentation to draw the attention of adults”.

[6] Writing retrospectively about the song, Can't Stop the Pop said Still on Your Side is a terrific follow-up that amply demonstrates BBMak's debut single was no fluke.

The group was smartly pitched; they toured extensively with Britney Spears and *NSYNC, which neatly aligned them to the bubblegum pop demographic.

[7] Additionally, the song is said to be "a welcome opportunity to cut loose with some triumphant ad-libs ('Don’t you know that I’m still on your si-i-i-ide') and screeching electric guitar riffs".

It is set in a New York City street and opens with two Italian-American moving men trying to lift a wardrobe up to an apartment.
