Annoyingly, I can really only remember the chorus. It's a super-chirpy girl-group pop song, with a chorus that goes, "But oh no!/ What about that?/ Ain't nobody gonna care about that! Oh oh!"
A google search does not bring up any song with those lyrics. It's entirely believable that this is just my brain coming up with inventive ways to get me to chill out, but if you happen to recognize this song as something that actually exists outside my head, please let me know.
