Actually the music I am getting is from

1)HL2 this way there is no download!

2) Completely original tracks that users made with the intent of having them appear in the upcoming game Black Mesa Source

This is so that the music will sound "new" and achieve a very selective sound. I want music that can work with zombies and on any map setting.

If you can get me a link to some doom stuff I could take a look at it, the one thing I am also looking at is trying to keep the download time short.
