There's no way I can gel stuff down to a "top 10". Too broad. Depends on my mood too, as in, some music is better for some moods and times than others. I like most all of it. I have a hard time classifying hard-core rap (with no melodic content) as music though. Guess I'm just old.
????? Disco...disco sucks.. ????? quack, quack

(but it's still a "nostalgia thing" and even bearable at times)
Most classic rock is good.
But like Tibs demonstrated...as soon as you make one list, you've omitted so much good stuff.
