One of my favorite instrumental sets of music *must* be the complete Final Fantasy VII soundtrack. The music fits so well with the story that just listening through the four cds worth of synth lets you relive the game in a time period only slightly shorter than the 70 hours it took you to beat the damn thing.

The CD is on iTunes here. On the rare occasion that my phone is set to ring, my ring is a shortened version of Rufus' March. But Aerith's Theme and Fight On! are my favorites.

Buy the whole thing, not individual tracks. It's $25 for the entire thing or $.99 per song for... four cds worth of songs.
