A Fairy Tail related question

OK, just because I wonder this a LOT, what do YOU guys think would be on the iPods or mp3 players of the Fairy Tail cast??? Some I would expect are:

Lucy: Extraordinary - Liz Phair
Erza: Most Paramore songs
Happy: Most bubblegum pop music (AKA, Disney stuff)
Juvia: Bad Boy - Cascada

That's really all I can think of...
