Buying CD's in Panama...? (Panama City)

I'm not a big fan of downloading music, especially since my iPod was stolen recently...so I was wondering if there are any CD shops in Panama City??? I've looked in Multi Plaza, Multi Centro etc and I'm not finding a lot of luck. I know there's like a relatively small book store on the ground floor in Multi Plaza but it didn't have a huge selection of English music...I guess I'm looking for a Virgin Megastore or an FNAC :) Wishful thinking, I know!
