Masquerade, for obvious reasons (huge Phantom phan over here)
Oasis tends to get a random Oasis song stuck in my head
Harem leads to the Sarah Brightman song
City, Sara Bareilles (or possibly the "I'm going leaving this city" line from Oasis's Go Let It Out)
and finally, cards like Mountebank always make my brain go "whatchu gon' do wid all dat junk"
