I just want to say thank you so much for this mod! It is friggin awesome all the work you have done, and it really does feel very metroidy.
I've compiled a list of which Metroid music I am currently using, if you are interested you can see the list below, and a link for downloading this mix;

Original message;
I don't want to seem too crazy with feedback, but I've been mulling over the soundtrack, and in the end I replaced some of the .ogg's with my own music selection, thought you might be interested which ones I've picked and why.
The big changes are;
- Making all of the egg tracks into Metroid 1/2 tracks (8 bit style)
- Making the rest from the 2D/16bit era (Super Metroid, Fusion, Zero Mission)
- Giving 7 different shop themes as opposed to 1 (although in some cases this isn't that great, Metroid doesn't do brothel music...)
- The ones I think work really well are the jungle selections, some of the temple ones. I really like the SM Norfair Ridleys Hideout theme for Hell, it reminds me of MP1 magmoor caverns (because it's a cover obviously).
A lot of the changes are semantic/superficial, but I thought I would share this if you were interested

Keep up the good work!
Cheers,
MrBlack
