Question about rights, royalties, and people re-recording your stuff.

[Mavfin]

As long as credit is given, and (if something were to "happen") any royalties handled.

(obligatory IANAL here. Tris, you lurking anywhere around?)

I would just say make sure you get credit and your part of any songwriting royalties if that happens, and let them have at it, but, I wasn't in the band with them, so, only you can really answer it.

If they don't want to do the above, then tell them you won't give permission to play the songs you cowrote. They'll have to use the ones you didn't help write.

If you want an agreement, make sure it's in writing, and have it reviewed by a lawyer.
