The Touhou Project really gets a lot of great pieces of music for being made up by a single guy with a synthesizer. To put the sheer number of remix CDs in perspective, there is a torrent which weighs over one terabyte (specifically 1.8 TB or 1,817,738,246,162 bytes) of over 3000 Touhou remixes, and that only includes the ones that the (English-speaking) maintainers of the torrent have added. It would take over a decade to download over dial-up, and it's getting bigger as more remixes come around.
