Sonic The Hedgehog CD

This soundtrack has been digitally ripped from the original Sonic CD game disc.
With the exception of the Past Zones tracks, all the others are bog standard Redbook Audio CD tracks you can listen by yourself just by putting the original game disc into a normal CD Audio player. You’d get the exact same quality as the ones here.
The Past Zones tracks are PCM as well so, again, nothing special about them.
They have been digitally ripped using vgmplay.

Someone could make a point that we should have recorded them from a Mega CD, but since the sounds are not synthesized, but sampled, there’s no point really.
The composers most likely made those tracks on a DAW or, more probably, with a keyboard workstation, a couple of external synths, some AKAI samplers and a sequencer.
I’m sure they didn’t bother “mastering” the tracks for the Mega CD as there’s not a strong low pass filter on the PCM side (the Ricoh RF5C164A chip) so there’s no point really in degrading the soundtrack quality by ripping it via analog outputs: a digital rip will yield a superior sound and be much closer to what the composers intended.

If you have the original disc or the anniversary OST, there’s no point in getting this, really.

The tracks are ordered following the official SEGA OST and not the order of the game disc.
Track titles have been taken from the official SEGA OST as well, there might be some very minor differences from the other releases (ie: Special Zone -> Special Stage).

If it wasn’t clear from the album art, this is the EU/JP version.
