Same here. I listen to a large variety of music, but I recognize that 90% of what I listen to is of no interest to folks here. Hell, the few songs I do post nobody really gives a shit about, I just can't help myself and feel the need to throw in some curve balls here and there.
I mean, it's not outrageous that age has a fairly large impact on ones musical taste. There's a reason I don't see much mumble rap posted here.
Obviously doesn't dictate all musical tastes but Id be willing to bet a large sum of money that there is a direct correlation to the songs posted compared to the average age of the posters.
