One person picks songs, and other people in the lobbies can request songs, then you all play the song at the same time, and see each other's scores at the same time. You can also see each other's avatars move around during song picking, and even in-game if you enable it.

At least for the MP lobbies hosted in the thread on thursday NA nights, we just shoot the shit in voice chat and play on no fail mode, and you can select your own difficulty on songs with multiple difficulties. No pressure to be good at all, just listening to music and hitting blocks. That being said, most of the interesting songs to play are usually mapped around expert difficulty or higher, so it still helps to be at least that good. We've also done newbie nights though with a selection of easier songs.
