A music based game where you wander around town and record sounds to make a mix with. Collect as many sounds as you want and then create the best possible song you can to try to please the audience at a club.

Punk-O-Matic

This is a flash game where you can compose your own punk songs. Use a guitarist bassist and drummer and a large variety of rhythms for each instrument to make you own songs. You can save up to three while you are accessing the site.

RockToons.com

A great site where with enough browsing or for a dollar a month you can find wonderful cartoon pictures of your favorite artists.

CreateBands.com

Not as good as Punk-O-Matic, but this is another site where you can create your own band and make your own music. This has a variety of characters and instruments that you choose from instead of the set three in Punk-O-Matic though.

This ones pretty self-explanatory: its a site containing song parodies.
