So some of the music in PSO is classic right? Not gonna call out any areas like caves, but some of it is also very stale. I really enjoy playing with music that keeps the same feel of PSO, there are some songs I've heard that just beg to be enjoyed alongside this game. That's what I wanted this topic to be about, the tunes you've found that go best with the game.
I'll list an artist and then specific songs, but follow whatever format you'd like. I'll look forward to checking some new music out and I hope you'll give mine a play also!
Squarepusher - Beep Street, Welcome to Europe Squarepusher Theme, Theme From Ernest Borgwine, I Wish You Could Talk, Welcome to Europe, Male Pill Pt 13
Agobi Project - Balance
Royksopp - The Fear, Silver Cruiser, In Space, The Alcoholic
Sonmi - Salem, Cold Welded, Yoona-5
P.S. I tried to search for a topic like this before making it so hopefully there isn't one floating around. If so feel free to axe this and I'll post there.
