this one because I used to listen to Limp Bizkit on my Mini Disc (MD) player while taking the train daily to my office in downtown Tokyo. I don't know what it was but this music used to give me energy when I needed it. MD is something I don't think ever took off here in the US. Super popular in Japan though. I used to record from original CDs to the MD on my home audio setup and make the "mixed tape" type of collection. I wish I would've kept that portable Sony MD player, maybe it would be worth something.
