Travis Barker (rawks), where can i buy?

frankly, i'm fed up of illegally recording his stuff off sites like youtube. i want the real thing. in particular, remakes of the songs flo rida - low and Soulja boy crank dat. i was thinking maybe hmv? i want to buy a cd with several tracks (hopefully including the 2 above), not singles/buying seperately off the internet (buy & download).
