That's not a "sort of license" - that's you touting for business. When you say we can have a look at your stuff then post an entire library of downloadable tracks, it's safe to assume that you might be putting them up in the public domain for people to use with accreditation.
I should probably draw your attention to:-
http://incompetech.com/ (Royalty free commercially, all you need to do is mention his name)
http://cyber-rainforce.net/english.html (Same, states on his site you can use freely)
etc etc, there's loads of royalty free music out there.
Generally creative commons stuff falls in to a bunch of license. The most common are:
CC0 - you sacrifice all rights and it's fully in the public domain for use without accreditation.
CC-Attribution - you allow your music to be used freely, but with accreditation to a specified person
CC Attribution Non Commercial - free use with accreditation and not for use in commercial projects.
If you're trying to make a name for yourself, I recommend CC-attrib.
