This song is one great song. I mean who woudn't like it? Ok some people don't call it real metal, but who cares. What matters is the song, not the genre. I woudn't know how hard it would be to turn a song into 8-bit.
The work that must be done to do this. Maybe it's easy. Maybe it's not. I don't know. One thing I will say is that you've done a good job of doing that. Well deserving on one of the top heavy metal lists. I woudn't call it "heavy", but whatever.
If you can reply to this please tell me how hard it is to turn something into 8-bit. Until then keep making these versions of popular songs. And not Hanah Montana popular.
