Well in music and in writing, I tend to like stuff that’s straightforward and stripped down. So the question is always “Does it serve the piece?” I’ve had to cut some of my best lines (or put them in something else) because the answer was “no.” So, like, a song can be ten minutes long if there’s a reason for it to be. Bobby Womack does a version of the standard “(They Long To Be) Close To You” that’s 9 minutes long. It’s really simple, but the nine minutes all serve the piece. But, say, “Freebird”… There’s three minutes of great song there, but it’s nine minutes long. Do you really need to have three solos? No. So cut that shit.
