I've been thinking lately...and I've come to the conclusion that music is like sex, but with certain advantages:

1)It's easier to convince people to form groups.
2)No one minds if you do it in church; in fact, some people might applaud you for it.
3)You can do it in public.
4)Getting paid to do it isn't illegal.
5)Doing it with family members is socially acceptable.
6)Doing it with members of the same sex isn't disgusting.
7)People don't mind as much when you watch them do it.
8)It's a subject no one minds talking about (unless you have melophobia...).
And lastly, 9)The orgasm is much longer.

If I think of more, I'll lengthen the list.
