One of my favorite computer games when I was a child was Quake. Everyone knows I was a huge Doom fan, but Quake was something different. It felt like the next generation leap to full 3D, and with it it brought actual CD-quality music thanks to Trent Reznor and Nine Inch Nails.
I would regularly pop the game disc into my CD player, skip track 1 (data track) and just listen to the rest of the album. The title track, heard here, is probably my favorite.
Thanks to Tyler for reminding me how awesome this soundtrack is!
