Trax-n-tabs site contains over 600 Backing Tracks and Music Scores / Guitar Tablature and new titles are being added every months. These are NOT backings made by taking the vocal out of MP3 files. These are all made by MIDI files. Originally they were started as pure guitar Backings, mainly for music by the Shadows, The Ventures, Spotniks etc. but this evolved and now we have Backing Tracks for Roxette, The Scorpions, Nightwish, Vanessa Williams, Dire Straits, Yngwie Malmsteen etc. All the demos have the melody replaced by guitar (because we are guitar players!), but the melody could be played by anything including using them for Karaoke.
