Yep, a fan-made instrumental of pretty much my most-listened song to date, Daiki Kasho's “5OUL ON D!SPLAY” from Gran Turismo 5 (and 6).

This instrumental isn't made by me, btw. It was done by a Japanese YouTube user who is now gone from YouTube, taking his videos with him, for some reason. (And no, it wasn't due to copyright takedowns. Seems he left on his own accord) He did this instrumental on Xewton Music Studio, which is a paid iOS app that can be found here: https://itunes.apple.com/us/app/music-studio/id328608539?mt=8

Other than the wrong bass note on the last part of the chorus and some audio errors throughout, the dude did a good job doing this on a mobile app.
