It’s pretty common for people to get upset when their favorite websites undergo a huge redesign. So the folks behind Last.fm must have been nervously anticipating a backlash when they launched a new look for the site this week. Sure enough, the Last.fm forums are full of complaints. There’s even a “Fuck the new Last.fm” group for the disenchanted, and the picture decorating this post is an avatar that a growing number of users are adopting.

The most common complaint so far is that the site is running far slower than usual. If you can get it to load, then you’ll find a host of new features. You can build up a library of songs on the site, and the home page now shows all your recent activity. But with Pandora reaching new heights of popularity thanks to its iPhone app, the developers at Last.fm couldn’t have picked a worse time for their site to slow down like this.
