I think it's cool as hell if it can be pulled off without everything sounding the same. My jam band does it, 90% of what we play is in C, mostly b/c we're in dropped D tuning, tuned a step down. No 2 songs of ours sound alike......We are intentially doing this as it is an artform, but I just can't find the term or name of the artform.

And it's NOT called boring, and we do know more than 3 chords.....
