[quote name='ITDEFX']thanks for the heads up...Sonic 2 Adventure OST WAS released. Picked it up a year ago from the Virgin Megastore in NYC

The US release of the SA2 soundtrack does not contain the full OST though, it's more of a "best of" selection, but with the added vocal tracks.
The true soundtrack contains every musical selection in the game (not SA2: Battle though, as that version was released later than the OST and had maybe 6 extra songs), minus the vocal songs, which were released (along with karaoke versions) on a seperate CD alltogether.
Sonic the Hedgehog and Sonic the Hedgehog 2 never got a proper CD OST released.
Look up some of the Dreams Come True CDs though, they are the band that composed the music for those two games, and a few of their songs are similar. They actually put one of their hit songs into Sonic 2, as the ending theme. It's called "Sweet Dream".
Sonic 3 & Knuckles got sort of a remix CD, but the whole thing was recorded from what I guess can be described as official MIDI remixes--I once had a MIDI synth that sounded *exactly* like everything on that CD.
I know way too much about Sonic the Hedgehog music.
If you ever look on vgmusic.com, you'll likely find a bunch of sequences I've made (lots of Sonic ones, of course, too).
