Associates
Frontalittle Squad - They used to make songs, but I think they're all playing Dungeons and Dragons right now.
Andre Desrosiers - Andy knows his way around a guitar. He's probably cooler than you.
Communities
Songfight! - Brutal weekly song competitions.
Remixfight! - Just like Songfight, only not as talented. I submit stuff here under the "Snyder Conglomerate" moniker.
Mixposure - They review your music, real nice-like. But they expect you to return the favor.
Resources
Acapellas4U - Providing you pass inspection, great selection of acapella tracks.
Juno Records - Buy and hear MP3 previews of thousands of CD and vinyl releases.
BadMovies.org - Sample-licious.
DeLarge - Check the "beats" section for some excellent hip-hop instrumentals for scratching, rapping, etc.
Recommended Listening
MC Frontalot - Nobody fronts more effectively, or more frequently, than he.
The Herbaliser - Spy-jazz hip-hop. Pure class.
Anticon - Fantastic artists on this label.
Jurassic 5 - Progressive old-school hip-hop and Chali 2na. What's not to like?
Dilated Peoples - More in the vein of J5. Except louder.
Tabla Beat Science - Free your mind, or something.
