If you haven't heard much De La Soul, then you may be interested in the 20th anniversary mix that Wax Poetics magazine and DJ Chris Read did recently for the album "Stakes Is High"[1].

As far as I know it's legal, and it gives a great introduction to the group's style (It's also my favorite De La album!).
