into our minds and into our hearts

It goes out into the world, to be merged alongside all of the other sounds, until it can be recycled as "new" music and you can enjoy it again:-).

As someone with a degree in Philosophy, I don't think this is really a philosophical question. The science is interesting and useful to know

It goes into the ears.

"And can you please tell me, oh

Where do broken hearts go?
Can they find their way home
Back to the open arms
Of a love that's waiting there?
And if somebody loves you
Won't they always love you?"

Really reminded me of this - the incorrect, useless, but poetic answer could be that it's just like with love. Into the open arms of the music thats waiting there.

This goes there.

It goes straight up my ass!

Tell the truth in simple. I was annoyed to learn that there aren't any crawlies that go back up your throath if you swallow toothpaste.
