not really listening to mixtapes much since they sound quickly made and low quality, but there is one exception to that rule: Crooked I. Every mixtape he makes I enjoy like it is a real album. I highly recommend you download his latest 'psalm 82:v6'

Downloaded it a couple of weeks ago and since then there barely is a day i didn't listen to it!
