Songbird 1.1 for Android brings lock-screen widget and Honeycomb support
Speaking of widgets, the Songbird team have been working on increasing widget stability and responsiveness, so if you thought it was a bit of a sloth-like affair before, perhaps this will be the fix you need. Bluetooth car audio support has also been added along with better bluetooth headset disconnection handling.
Songbird 1.1 may be out the door, check the source for full release notes, but the team are already hard at work on the next iteration, which should feature landscape support among other things. Head over to the Android Market to get your free Songbird 1.1 download.
