The conventional idea is a band makes a CD of their songs, mastered to perfection, stamps out CDs and streams, and that's it. The exact same audio, let's call it the "radio edit". I hear the song on the radio, it's exactly the same. I can tell when a performer is lip syncing, because no singer sings a song the same way twice, and I know the radio edit. It's burned in my brain.
But, I discovered that when real bands, like Fleetwood Mac, play a concert, they play their old standards, but in a different way every time. I bought their concert CDs, because hearing different versions of the same song makes it fresh and fun again.
So my idea is, why don't bands produce a dozen or so "radio edits" of their better songs? I bet they'd increase sales, especially to people like me.
I suppose they think they are doing that with the "remastered" edits, but those all stink. Sing it again, Sam!
