This music plays in the ruins area. The previous port had the pianos sound like they're playing two notes together at certain parts. Now with SEQ64, this port sounds so much better and fixes all of the issues.
This music is played on Toad Town Ruins in Mario and Luigi 2 : Partners in Time. This is a remake of one of the first M64s I've ever made, a bit more accurate to the original and contains a version with drums ^^ ("default" has them only at 2nd loop !)
