Over the weekend we rediscovered Last.FM, but what got to us was the fact that we could only listen to the tunes through our computer speakers. While we have an Airport Express, that only lets us stream audio from iTunes. Kind of a bummer if you want to stream audio from other sources like a web browser. That's when we discovered Airfoil...

Airfoil is a third-party software download that lets you hijack audio from sources like a web browser, Real Player, Windows Media Player, and Quicktime and wirelessly transmit them via your airport express to your speakers.

The software costs $25 and is worth every penny.

Do you guys have any other solutions for wirelessly transmitting music to your stereo?
