is all the usage here NonCommercial? I’m looking for tracks which permit Commercial Usage…like at Free Sound Project. Nothing like that here? Anyway to search for it?

There’s a link over the left ‘Looking for…?’

Click on that.

Then, for remixes see ‘Browse Remixes’ and select the ‘attribution’ license in the remix browser.

For samples, see ‘Browse all samples’ and select ‘attribution’ in the sample browser.

For a cappellas see ‘Browse a cappellas’ and select ‘attribution’ in the a cappella browser.

I do a similar trick. I go to a sample I know is BY (and thus ok to use commercially), like this one:
http://ccmixter.org/files/n...

and then I click on the tag “attri bution”, and voila! I get a list of such material. a bit more lo tech, but it’s easy for me to remember how to do it that way.
