One of the upsides of using iTunes is the playlist feature. With it, you can create great playlists that will allow you to listen to all your favorite tracks without having to switch from album to album.
But, what if you just put together a great playlist and you want to listen to it on all your computers? Well, that’s where Echodio.com comes in. With the site’s innovative service, you’ll be able to keep your iTunes playlists synced between up to three computers. What does this mean? Well, you’ll be able to enjoy your favorite songs at home, the office, and anywhere else you can think of.
The site just recently launched (with some funding from YCombinator), so the service is limited to iTunes 8 and Macs. Beta testers get up to 1GB of storage, or about 178 songs, which is just about enough to keep you entertained for a whole day. Every time you make a change to any of your synced playlists, they’ll be automatically updated on your other computers, making for a great music listening experience.
