Attention, Readers: Help me find good new music, please

I know this is off-topic, but bear with me. For Xmas last year, my little brother gave me an iTunes gift card. I’d actually not used it yet, and I just ran across it in a drawer. Since we’re talking about music and iTunes today, I figured I’d let you guys pick out my new music.

See, I need something new. I’ve had the same 400 or so songs on my iPod for about three months now. I have Imperial Teen, The All Girl Summer Fun Band, Band of Horses, Sonic Youth, The Jesus & Mary Chain, Pulp, Metric (whom I’m seeing tonight), and My Bloody Valentine, among others. That list will hopefully give you a compass as to where my tastes lie. So I ask you, readers with taste, what should I look at?
