I don’t think anyone has yet mentioned that many of the songs are chords from standards, with changed melodies. I know this is true of the early jazz song demos. I could easily identify the song, and save the song under the ‘right’ name then remove the demo melody. Sometimes rhythm patterns or hits are missing because they would be distinctive and perhaps invite a copyright claim.

I don’t know if the other genres are this way. I also don’t know if most of the jazz demo songs are chords from standards, because I don’t claim to know all the standards.

PG Music does say somewhere that you can use what you create but don’t use the demo songs - words to that effect.
