Songbird is hosting the next in our series of Media Web Meetups next Tuesday, December 11th.

This one promises to be awesome; we’ve got some heavyweights in the realm of portable playlists coming over to have a panel discussion about the future of how music lovers are going to listen to their media on the go.

On the panel so far: Tantek Çelik (former Chief Technologist of Technorati, and microformats expert), Lucas Gonze (XSPF and portable playlist guru), Scott Kveton (Open Technology Lead at MyStrands) and Tom Conrad (CTO of Pandora).

Wow! How star-studded is that cast?

The panel starts at 6pm at our offices here at 585 Howard, but Lucas will be giving a one hour talk on XSPF and the history of portable playlists to provide some context to the panel at 5pm.
