I need tunes at work

Sites like Pamdora are blocked here but it seems some artist sites music is allowed such as The Cowboy Junkies and recently found I could listen to what Sade has.
Not sure why their music makes it through our filters but my question is...have other hard working folk out there with similar blocking of streaming audio(like my Pandora situation)found artists that have complete songs available that perhaps would also sneak through to me? Not looking for any particular genre as I am always open to new tunes.
