I like ARTWORK of course.
FEATURES should be limited and should vary from genre, rappers/singers, region, affiliation, rookie/well established.
I like to buy from artists who appreciate support and aren't cocky or dicks when you try to have a conversation with them whether in person or online.
I wont pay more than a dollar per track on a CD so it better be more tracks than the dollar price for the album.
Definitely releasing videos, or snippets is what drives me 2 buy a cd. I've took risks and bought cd's that i honestly regret buying, because i didn't preview and i was bamboozled because the cover was tight as fuck, but tracks were Garbage
