Musical themes changed?

Yo
I haven't tried to go in any dungeons for a couple weeks, and game soundtracks now sound totally different to me, were they remixed?
I know this is one not very interesting thread, but they actually sound even better now!

Changed of loudspeakers actually..wow, could be I'm just discovering what soundtrack actually sound like LOL.
Back in the Nintendo 64 days, I did not realize the family TV had only one speaker. So I left very video game's sound settings on Stereo or Headphone mode.
I didn't think much of it.
Later, I replayed Ocarina of Time and, perhaps by accident or perhaps finally noticing there's only one speaker, I switched the sound setting to Monaural...
Suddenly, songs had more than one track. My mind was blown at all the harmony lines I'd been missing out on.
Maybe I should replay more old games to hear the "missing halves" of their soundtracks...

Ya lol actually it sounds totally different, like my loudspeaker were filtering some frequencies -oo-
I haven't noticed any difference. Maybe something on your system changed?
