Watch this melodica player follow cosplayers while playing character's theme song

LilyPichu went to IndyPopCon with a melodica, then followed random cosplayers around while playing the songs from their game, film, or show. The different reactions are priceless.

Can you name all the songs? I missed that tricky one in the middle, which turned out to be Darude Sandstorm.
