Words of wisdom for all of us! I recommend following the advice of the Set List Lord, this is useful stuff to know.
Especially the one about always knowing a band's prior setlist! The info is all right here, folks, and though I've never heard Dark Tranquillity in my life, I managed to nab their entire setlist!
As I told Pavo, setlisting is an art, and it must be done with the necessary precautions in mind. Most of all, have fun with it!
