Musicians - these people seem almost to-a-man incapable of thinking in terms of a show. They are in show business, yet totally lack any ability to start with the concept of what sort of show they are going to produce. They sit around, scratching themselves, waiting for inspiration and for 'that great song' (that never comes!) instead to doing things the right way about. You start with a show and a concept for that show, THEN work out what sort of sounds you are going to make (metal, pop, prog-rock, whatever) - then and ONLY then, think of the tunes. That's why acts like Gaga, Rammstein, Beyonce, Pink, etc., are successful across the whole of planet Earth. They think of how to put on a show FIRST!
And before you think of a show and what they show is going to look like and sound like, you have to have something to say. Gaga, Rammstein et al have something to say.
I have sat down many times with musicians and they have told me that they are trying to compose a song, but are having difficulties. I then ask them, what are they trying to say? What are they trying to tell the World? Are they writing about death, love, relationships, lost dreams, lost youth, what?
"Er, well, er, um . . ." and that's about it.
"I don't think we actually have one message." they mumble vaguely.
I tell them, no yearning need to tell the World that something's going on - no message. No message means you have nothing to say, so no show. No show, no sounds, no music and no tunes.
