For some reason I tend to always use 4/4. The tempo can range anywhere from about 58 to 140 bpm depending on the style i'm writing. But it makes me wonder am I limiting myself? I just find that whenever I go for 3/4 or something else it just doesn't work as well. My music still varies quite a lot and no two songs ever sound the same.
How about everyone else? Do people see writing in 4/4 exclusively as a big problem?
