Thankfully, there's been more of these than the worst ones from that other thread, but I'll only mention one.

Back when the celtoid band I play with was doing some original songs, a festival audience was actually singing along with the chorus to a song I wrote, without prompting. They knew the words from our cd and other shows. That feeling is indescribably cool. The singer (not me) acknowledged me when the song ended, and the crowd was so generous I thought I was having a religious experience. No amount of money can buy that feeling.

Peace. Mooh.
