GHTunes

"GHTune" is a music studio for Guitar Hero that allows you to create and download music. Similar to the use of Mario Paint but with the ablility of being able to play the song such as Synthesia, with the use of plastic guitar's drum's and microphone. Most songs being created are from popular cultures and many have been made, recorded and uploaded to Internet video sites such as Youtube.

Wikipedia's Description

The Studio is similar to Apple's GarageBand software. The player can create the tracks for each song by playing it in real or slowed time, with the game quantizing offbeat notes to the nearest beat as set by the player, or tracks can be constructed one note at a time. The notes played by the user will be the default "Expert" difficulty track, and the lower difficulty versions will be generated by the game.
Players can create the tracks for lead, rhythm, and bass guitars and for drums, selecting from a number of different sounds and kits for each instrument. Distortion and other effects can be added to these tracks through Line 6 amplifiers in the "GHMix" mode. Players cannot record vocals directly, but can create a hum-along vocal line in the Studio.
Custom songs can be uploaded to the "GH Tunes" service, allowing other players to rate songs and search and download songs by these ratings. A Showcase service provides some of the best user works alongside new songs from popular artists for players to download. Bright has stated that uploaded songs will be actively monitored, and that covers of copyrighted songs will be removed from the service while also taking down any other requests made by copyright owners.
