Songbird worked alright for me with windows 7. It was the latest one as I downloaded it last night.

I did however have some problems, whether they are bugs or not I don't know but when I initially connected the n900 it wanted to prepare the device and then I synced a playlist and it deleted all the default music and ringtones.

The other issue and maybe it is just my settings or I need to do something differently is it dumps on the music in the data folder. It would be nice to specify what folder on the device you would like to send the library to along with the playlists.

Is there something I am missing with some sort of setting? I couldn't find where to change the output other then to put
artist/album/title but then that still dumps all the folders in the main directory.
