I'll throw out what my roommate and I did too. We did essentially the same thing, but it plays music from rdio, or whatever songs you have on an iPhone/iPad/iPod touch.
It's up at http://letsparty.fm. Not quite finished, but definitely usable for our purposes.
Thanks! At the moment it randomly selects a user with one or more songs queued up, and then picks their top song. I think that I will refine this though as sometimes someone gets picked 6 times in a row and everyone complains. Especially if that someone is me, it looks suspicious...
Cool, I'll check that out. How long ago did you release it? I've been looking for something like this for ages.
Maybe you could order the users by how long they waited to have one track played. This way, everyone has the guarantee to be able to play at least one track.
And thanks! It's not released officially yet, I'm still hacking on it on weekends, and beta testing it in parties. I may post it on hacker news when the spotify integration is ready
Since you show the upcoming songs in the playlist, you could consider using that information in the queueing: explicitly order the upcoming songs to rotate between people, one song per person, with everyone getting one song before anyone gets a second.
How do you "fairly" pick between queued songs? Do you rotate through every user one song at a time, or is there a scoring system involved?
I made something similar, but with the music coming from deezer instead of youtube, if you want to check it out : http://poll.dance
