In the spirit of Brian , I will now nominate a lesser known act that I think ranks up there.
Cody Chestnut- the headphone masterpiece This track is typical of about 1/4 of the album.. it ranges from R&B like( the artist formerly known as)Prince to hip hop with the lyrics ranging from love songs to very humourous takes on relationships to the very profane....the range is great. Derek will know one track that is on the soundtrack to You me and Everyone we know by Miranda July which would make my top 10 movies of the decade, but I digress ..Definately the cd is one of my top R&B / rap type albums....
