If I'm not mistaken, iRealPro has a ton of songs (chords only, for legal sharing) because users entered them into their format and made them available on their website.

BIAB is a little different; there are BIAB-formatted songs to be found on the Internet, just not on the company website.

There are also perhaps more standards than you may think already shipped as demo songs with BIAB; they just have no melody and use a fake name to avoid copyright problems. Once you play them, you should be able to identify from the chord progression what the original song was, and rename it.

And then there are public domain songs versus those still under protection from copyright (in the USA, anyway) ...
