To be the best, a music store has to carry a vast selection. For those whose tastes run all over the board, you can find everything from your favorite Jello Biafra or Henry Rollins spoken-word CD to Peter Allen's At His Best. You also will find everything in the middle -- jazz, hip-hop, industrial, rock, R&B, dance, rap, blues, imports, boxed sets and, of course, Elvis. Whoever orders the Latin music should get a raise; it's not limited to Ricky Martin and Jennifer Lopez. Soundwaves also boasts one of the largest, if not the largest, preowned CD selections in Houston, which you probably already know from the buxom yet "flat-busted" women from the television commercials. The store also has a peculiar section with skate and surf merchandise, but before heading over, you may want to surf to www.soundwaves.com and pick up the $1 off coupon.
