I should have mentioned this, but I know it's not the headphones because if I play a Minidisc that I burned a few months ago, the tracks sound fine. Even if I copy new songs onto an old disc that still has music on it, the old songs will be fine but the newly transferred ones sound messed-up. I use sonicstage and record in LP2, all settings are default.

I dont know what happened but now eveyr song I transfer to my Minidisc player (Sony MZ-N510 type s) the song sounds like the singers are singing underwater so to speak. there are random bubbling sounds through the entire track and it cuts in and out. is this a common or even heard of problem, and is it fixable?
