It depends.
Myself I am a fan of 8-bit music but only in the sense that like all music, it has evolved. Sure you have your 8 Bit Weapon and ComputHer providing the retro stylings of original videogame music, but then you have artists such as She or Machinae Supremacy who use the 8-bit sound to add to the music rather than consist of all of it.
While I enjoy listening to remade or brand new retro stylings, I prefer new music with 8-bit sounds rather than a full 8-bit track.
For people interested, She and Machinae Supremacy have loads of free music for download on their sites.
