When I bought this, I knew a couple of Quest songs from youtube, but wasn't really familiar with their music as a whole. I'm very glad that I decided to give them a go, as every song on this compilation is great. It's (mostly) chilled out, positive hip hop with strong flows, good lyrics, and funky beats. You'll probably end up with duplicates of all the songs after it inspires you to go and buy their albums, but at £2.99 that's not such an issue.
