There is always the option of Royalty Free music catalog sales that can really accommodate any music style or even quality if someone were say looking for a garage band just starting out sound. Even though they may only use 20 to 30 seconds of your song they should be about 2 minuets.

Problem with Royalty Free music is that it takes a while for anyone to find you and there is very little money until it gets wide distribution. It's a gamble but for me I'm retired and it keeps me off the street when not doing CGI stuff on my workstation.
