Music is like sex in a lot of ways. Both are forms of communication that transcend words. Both push the limits of how much fun a person can have. And a good sense of rhythm provides greater pleasure to your partner/audience.
Recording is like romantic love. You should take your time to make sure you get it right. You should pay attention to every detail. You should communicate as honestly as possible. You should be aiming for eternity.
Playing live is most like sex: pounding and sweaty, the air filled with rough animal noises. You should be aiming for immediacy. When it is over you should feel drained and sore, having held nothing back.

Every musician I know became one because something burned inside them that they could not find another way to adequately express. Once we learned how to channel that burning thing into our instruments, we found ways to express other things – sometimes beautiful, sometimes horrifying – that were different from our original passionate urges. Sometimes we were embarrassed by that raw emotion, the way an older child is embarrassed by the memory of their infantile self. But, like punk rockers reacting to the excesses of progressive rock, we need to return to our inciting passion to keep from running dry.
“One more time,” the singer tells the band, “with feeling.”
Your stitches are all out But your scars are healing wrong The helium balloon inside your room has come undone And it's pushing up at the ceiling And the flickering lights it cannot get beyond Everyone takes turns Now it's yours to play the part And they're sitting all around you Holding copies of your chart And the misery inside their eyes is Synchronized and reflecting into yours Hold on One more time with feeling Try it again, breathing's just a rhythm Say it in your mind until you know that the words are right This is why we fight You thought by now you'd be So much better than you are You thought by now they'd see That you had come so far And the pride inside their eyes Would synchronized into a love you've never known So much more than you've been shown
