One thing that stuck me about Google Music is its lack of built-in support for last.fm. Was kind of hoping this had it.

Does Last.fm support mean just scrobbling, or are there other features you might like? I'm not a Last.fm user but I'd be willing to take a look into including support down the road!

Last.fm scrobbling was the first thing I looked for as well. It's pretty much a necessity for me at this point that any software-based music player I use needs to support last.fm scrobbling. There's several Chrome extensions that take care of it for the in-browser player as people below have mentioned.

I just fired this up, it looks and works great! If you did implement last.fm scrobbling (currently I just use a tampermonkey script that works well) I'd start using it primarily.

For me personally, just scrobbling.

At this point, that's the only thing stopping me from using it. Looks great, but I'm a stat freak and I need my scrobbling.
