Hey! I've been looking around and couldn't find the hidden music from Tetrisphere anywhere on here(That, or I'm blind).
In case you don't quite know or remember, the hidden music was only available with the 'G(alien head)meboy' code using the secret letters in the name selection.

Here's the link.

There is some very minor 'static' sounds in the tracks, nothing distracting. I didn't know how to fix that. Probably because it was directly converted from USF format, I dunno.
Anyway, enjoy!

Oh, I should also point out that the file info is completely blank on the tracks(Soundtrack name, contributing artist, etc). However, each track is named accordingly and numbered in their titles.

Wow, I never knew there was hidden music in Tetrisphere O.o It's one of my favorite vg soundtracks too. Coincidentally, me looking for that soundtrack led me to Galbadia Hotel, which led me here to the Shrine :p I found another site that has a track that doesn't seem to be in your pack. There's 2 versions of Sappy and one called Martist. I wish I knew more about this :( But thanks for the upload :)
