I still haven't been listening to much music at work lately (most of my listening these days happens on the train), but at least there isn't a 10 way tie for first this week at one song per artist. Here's what my Last.fm profile says I listened to the most last week:
The Arcade Fire
Black Rebel Motorcycle Club
The American Analog Set
The Hold Steady
In other music news, I'm just waiting for some new albums by Wilco and The National to drop, and looking forward to shows by The Arcade Fire, Ted Leo, Clap You Hands Say Yeah! and The National.
