Making a share-able playlist?

Hey guys. Does anyone know of a site where I can make an online playlist of sorts? A group of people and I might be compiling one from now up until the fall, so we can all share a login if that's an issue.

The only methods I can think of right now are a Google Docs Excel file (blah) or a YouTube playlist (also blah). I feel like there's something more sophisticated than that out there, but I'm not sure what's good/bad.

Thanks!

 

That actually looks awesome, but it's not out in Canada yet.

Thanks though!
