Often if a game's music is available, fan sites will either host it or link to it. If you like Metroid, for example, you can find some of the music on Metroid Database
. Look around and you'll find similar sites dedicated to many of your favorite games.
File Conversion, Downloading, etc.
I use DownloadHelper
to download YouTube videos, and SUPER or an old (when it was free) version of dbPoweramp to convert between formats. If anyone could suggest some good conversion software (flv/ogg/wav/flac/mp4 to mp3 mostly) that's readily available, leave a comment and I'll add your info here.
Coming Next Week
In Part 2 I'll be linking to some free, legally available soundtracks that you can just go download directly. I only know so many, though, and that GoG Free Soundtrack List
is pretty impressive already. Anyway, if you know any I should include, mention/link them in the comments and I'll be sure they are included. I'll probably list some game soundtracks that are flat out worth buying, too.
