Joe Wiewel's story pretty much sums up how I found vgm outside of a game. But I was humming videogame tunes since the days I was playing the first gradius arcades (1989 or so.) Only difference really was the fact that I first stumbled across the music at vgmusic.com in midi form. It was a exciting day for me knowing that I didn't need to play through a game just to hear my favorite tune. And it was even more exciting to know other people enjoyed that kind of music =p.
Then around that same time a friend of mine actually traded me the FFVII soundtrack for a couple new age cds I didn't much care for. I honestly thought I was getting ripped off, I must've paid at least 8 dollars for those cds. And for vgm? What was I thinking! But after playing the game myself I was quickly proven wrong. Of course I then scrounged for more of this music via napster, then aimster, audio galaxy, kazaa, and finally GFA.
Thanks GFF, now I have enough music to start a radio station

Jam it back in, in the dark.
