During an interview with The Matt Morgan Podcast, Liam's brother and bandmate Noel Gallagher called the track a "perfect" song.

Noel Gallagher stated jokingly in an interview with Patrick Kielty that Liam decided to "write a song about his bird", and states the title "Song... bird" in a cave man like manner.

But when Liam plays you a song he wants you to instantly f—king drop dead on the spot and then, when you come around, stab yourself in the heart and be in awe of the f—king sonic ability of the man.

"(You've Got) The Heart of the Star" and "Columbia" are B-sides, the latter of which was recorded live at the Glasgow Barrowlands, in October 2001.

[13] Doug Levy for CMJ New Music Report said that Gallagher had a "surprising talent for songwriting", referring to "Songbird" and album tracks "Better Man" and "Born on a Different Cloud".
