This! Are you a musician or just a freakin', lazy, live juke box?
The best band I was ever privileged to play with arranged EVERYTHING. We made medleys out of songs. We covered the hook on whatever instruments we had instead of whatever instrument played it on the radio. We sang harmony that highlighted our voices instead of theirs. We changed tempo, rhythm, style, arrangement, intro, bridge, ending ... whatever our (very talented) lead guitar player heard in his head and taught to us. And we played from our hearts.
We made music. Became local legends while having the times of our lives.
