Audity (aka: me, previously World-of-Ruin) made this mix after going through the 50 or so pages of remixes already on the VGMix.com site, as of its 3rd site design incarnation (VGMix X). Its content is generally energetic/fun, and contains a handful of source tunes that are well-liked to the gaming crowd, but it also includes a couple laid-back songs and lesser-known VG originals.
But that's not everything. While this is a mix from VGMix X, it also includes songs that might not even exist in a game, but sound like they could have been from one, like some of Virt's works that he presented at MagFest VI. Basically, it all comes down to the general theme of me finding new remixes as a result of VGMix X's conjoining itself with the community once more; if it sounded good, I kept it regardless of its origin.
Depending on which Bit Torrent client you use, you should be able to download either the FLAC or the MP3 individually, without having to do so for both.
As for the CUEs, your CD burner should have an option to load them, which will then split the music file into 22 separate tracks. I haven't tested them, so there's a chance some of them might not work.
