The best mashup can be transformative, musically. But add visuals that are both convincing, plausible and fun to watch, and you got "Alejandro's Song," which combines Gaga's "Alejandro" with Taylor's "Our Song."
The same people were behind the recent "Smells Like Taylor Swift" video mashup, which "teamed" Taylor with grunge-rockers Nirvana. Watch that one HERE!
