I know I've got complete discs in this torrent, but whether or not there are more OSTs is beyond me. Someone informed me in a comment on my Z Gundam OST post that there is a second set of OSTs for the movies. These are the series OSTs, not the movies. (I will look for the movie OSTs though)

Mobile Suit Gundam OST 1
Mobile Suit Gundam Special OST 1
Mobile Suit Gundam Symphonic OST 1

Note: There are two tracks in the MSG OST 1 that are a tad buggy. I appologize for this, but those are the only two that I could find. Also, on the Special OST, I added two tracks that I thought should be in there.
