Not so much steal my songs. But I have had little signatures and measures that I created that so-called "friends" have borrowed and put into their songs.One signature I came up with was a bass line that a "friend" put into his song as part of an extended solo break.
I've noticed a lot of guys have the thought process of - because they were involved in making a song, 'they' wrote it.
I had one song that I brought to the table complete - guitar, bass, drums, melody, and a wacky singer claim the song because he wrote some words and altered the melody slightly...
Whatever.
If there aren't more to come, then what's the point?
Eat all you want, I'll make more.
