GEMA Round 2: Tie Your Artists Down by Membership

This whole GEMA (Germany's collections society) apparatus of rules, conditions and rates really is complex. If I get anything wrong - be it either to GEMA's advantage or disadvantage - please tell me and I'm going update my article. Email me or simply post a reply below. I gladly will stand corrected. I don't know what it looks like with ASCAP et al. - I can't imagine it to be worse than here.
