Hi IGTians, I have been using Guitar Tabs With Rhythm | Songsterr Guitar Tabs and Chords for about 7 weeks now. Its like a web based Guitar Pro. You can find tabs and then play along with it. For the free/un-registred version one can only mute tracks and add a count-in before the track starts. I found the site to be really good. More functional than UG. Try it out!
