I think lesser known artists have better tools to promote their music to an audience who may not have heard them before. I think it also lessens profit to major label type artists because people realize there is more out there and they don't need to buy a whole album just for one song.

sure.

Nirvana, Nine Inch Nails, Cradle of Filth, Type O Negative, Stone Temple Pilots, Pearl Jam, Alice in Chains

Whatever is available.
