GWENWYN'S PROFILE

For music I use

http://freemusicarchive.org/about/
(along with 'creative commons music searches')

There's a lot of music thats allowed to be used even in commercial projects with proper crediting.

If you're adventurous and/or use parralax mapping, I'd recommend
http://www.cgtextures.com/
and
http://texturelib.com

It's amazing how much better things look in game with a little real world texture taken down to the right size and mapped over!

For sound effects
http://www.freesfx.co.uk/soundeffects

Really helpful for longer background sounds.

All of the above are licensed as available for use in commercial projects with proper crediting. Note that CGtextures has restrictions (namely, primarily for use in creation of games and models)
