Download all 3 CDs by "Halcyonic Falcon X"
Don't scroll down to anything else; I can tell you right now it's all either poorly done game graphics, or a CD cover (representing very crappy music -- I already sampled it) that makes Sailor Moon look modest. Just trust me.
The music by Halcyonic Falcon X is absolutely incredible though. There are probably 2 or 3 tracks out of the 20 that you might want to delete or set aside; the rest are amazing.
I guess it depends on what kind of music you like. But, objectively speaking, it's very melodious and good music.
