2.0 was initially released to coincide with SSNTails's marriage. 
That's surface level information though, so let's talk MIDIs. 2.0 
is the oddball hybrid between Final Demo and 2.1 with it's MIDIs. 
When I say oddball, the intro theme is impossible to find despite 
clearly being in the game. It also just doesn't have MIDIs that 
sound close to some of the new songs added. Most notably, Egg Rock 
Zone. Egg Rock Zone instead reuses its former act 2 theme for BOTH 
acts. It's... I'll let Vertz describe the song. (All you need to
remember is the fact that somebody keeps smashing their head on the
piano) 2.0 also introduced more music while getting rid of the 
Christmas stuff. For some odd reason the unused theme commonly 
associated with Wood Zone now has a different lead instrument. 
Like I said, 2.0 is certainly an oddball.

Vertz Commentary: When someone mentions the SRB2 OST, the first 
thing that comes to my mind is this soundtrack. It practically
embodies the complete legacy of the SRB2 sound experience, 
making it the closest representation we have. Don't get me wrong,
the new songs in 2.2 are fantastic and can definitely represent 
SRB2, but for those of us who have been familiar with SRB2 before
2.2, these tracks hold a special place in our hearts as iconic 
pieces that define the game as a whole.

Sonix's Commentary: Ah, 2.0. The first "full" version of SRB2 
released. I talked about Arrow's redone songs, so now I get to 
talk about the Mystic Realm's soundtrack. It's fantastic. One 
thing I noticed with all of the songs done by RedXVI is that they
 tend to have key changes. Jade Coast is a fun beach theme. Not 
too much to say on it. Tempest Valley. This one is fantastic. 
Sure, a lot of RedXVI's MIDIs have poor audio mixing, but I can 
excuse that if the song is fantastic. Tempest Valley is wonderful. 
I typically don't like songs that are too upbeat, but this one 
slaps hard. Verdant Forest reminds me of caveman music. Sort of a 
panicky feel to it as well. Flame Rift is just... insane. I suggest 
listening to it yourself. Midnight Freeze. This one wasn't done by 
RedXVI, but rather Arrow. It's a redux of his Ice Forest theme from 
Sonic: Emerald Quest. This actually wasn't in Final Demo. I made a 
remix of it too, check it out in the bonus MIDIs. I like it a lot 
though. Sunken Plant... not too much of a fan of it, probably the 
weakest link. Aerial Garden's themes are incredible. They have a 
feeling of adventure to them that fits AGZ perfectly well. Prismatic 
Angel's theme is orchestral and it's awesome. Nice foreshadowing to 
the titular Mystic Realm Zone, which has a wonderful theme, but it 
is... loud. Oh yeah the boss theme. It's a jam. That's all I really 
have to say.
