Spotify bitrate

[shenzi]

When listening to a music stream, is there a simple way I can check the bitrate being offered? (I'm on a Mac.) I'm using the Spotify.com music service and I've read that it's around 160kbs but am curious to check. Sounds good to me but then it is free.

 

P.S. Anyone UK-based who hasn't investigated it, go have a look. It's fun. I blogged about it recently and am now being accused by all sorts of people for causing them to waste their day tracking down obscure albums and artists...
