Like a theme?

I only remember two :[... It seems alot less common these days, oh wait, three!

Yoshi's Story... Did it okay, but it had an obvious theme -_- and it sometimes annoyed me a little.

Pink Panther something something Hollywood on the SNES, did it AWFULLY, The game was already awful, so it suited it perfectly I suppose.

Gauntlet Legends/Dark Legacy... It took me a little to figure out they were actually going with the same tune, it's a really nice OST ^_^... it became obvious to me in the Battle Areas (At least they traversed Epic,Rock and Techno through those) that the same tune was used in about 98% of the stage's music in the entire game.

So Uhhh, if none of this made sense...
