Jack Johnson, the author of many mellow melodies that’ll make you want to stay in bed all day, has figured out a really cool way to promote his new live album on Twitter.

It’s really simple: just head on to twitter.jackjohnsonmusic.com. There’s a premade Twitter message there (you can add 24 more characters if you like) that promotes the new album, titled En Concert, and all you need to do is login into your Twitter account and send it. The download of the promised tune (it’s a 192 kbps MP3) will start automatically.

This is probably one of the simplest and best examples of how a musician can promote his work via Twitter, because everyone wins: you get a free song off the new album, and Jack Johnson will probably get a free Twitter trend and lots of good vibes.

We received ‘Flake (Live from San Francisco)’ – let us know what tune you get?
