Mashups are my favorite things ever, and this playlist is a list of, in my opinion, the best that I haven't made - alternatively, the ultimate favorites and aspirations. This does not include covers (or even of the acapella sort), just excellent mixing plus actual excellent song/genre choices from the songs as they exist by themselves. Also, sorry for duplicating two songs (Sugar, We're Going Down; Boyfriend) but I think they're mixed differently in both mashups.
