When you do a tribute, cover or even a remix of an other artists song, I believe that, you have to honor and respect the originality, feel and expression of that track. By this I mean, that you have to take it to another level, and not just “do your own shit” of it.
All to many cover versions and tributes butchers the originality in those songs. Not just in your everyday music but also in the chiptune community.
That being said … I have gathered some cover songs from different artists, which I believe live up to being a great cover version and a tribute to the original song. Your opinion may differ
