As an XNA creator's club member, and an avid musician, I've decided to start advertising myself to local bands as a means of getting their music into Rock Band 2. I've explained to quite a few bands what the Rock Band Network is, and worked out deals where, to save them the hassle of learning the software or paying the creator's club membership fee, I would chart the songs and publish the songs for them.
My question is, is there any legality issues I should be concerned about ? These are all local unsigned bands, with our own worked out contracts. If a band has had a professionally recorded album, does the studio that recorded it own any rights to those tracks that would prevent the band from letting me use them ? If so, I have the equipment to do fresh recordings.
Second question, to do this legally, should I apply for something like a small business license, or am I still within legality by just doing it on a personal level with the bands ?
Thanks for the help.
