Is it normal that good music gives me a boner?

I get a chubby on when I watch a Katy Perry music video.

Is that what you mean?

You've got a friend in me
You've got a friend in me
When the road looks rough ahead
And you're miles and miles
From your nice warm bed
You just remember what your old pal said
Boy, you've got a friend in me
Yeah, you've got a friend in me
You've got a friend in me
You've got a friend in me
You've got troubles, and I've got 'em too
There isn't anything I wouldn't do for you
We stick together and can see it through
'Cause you've got a friend in me
You've got a friend in me
Some other folks might be
A little bit smarter than I am
Bigger and stronger too, maybe
But none of them will ever love you
The way I do, it's me and you, boy
And as the years go by
Our friendship will never die
You're gonna see it's our destiny
You've got a friend in me
You've got a friend in me
You've got a friend in me
what has been seen can never be unseen.

oh yes, its is pretty normal to get horny with good songs

I had an orgasm listening to a live concert from a band I like once. It was surreal.

Eargasm.

I guess what you mean is how some music reminds you of being on the dance floor surrounded by hot women since when you last heard that particular music, that's where you were, and that's what gives you the boner. Is that what you mean?

What music does this? just wondering ....

I suppose it's normal. You can't control when you get an erection. Though I've never had the same thing happen.
