This is a big frustration of mine. I believe that part of the reason why we have all these crappy commercial music is because these producers also try to be songwriters. Maybe it happens that someone is so talented that they can do both very well. But in my experience it's really rare.
I've met many producers who are really good at what they do, but they undermine their own work by also trying to write the songs themselves. That's we got all these songs with decent melodies but terrible lyrics with absolutely no imagination like "let's go party and sip bacardi" or "tonight i'll make you mine, because you're so fine"...
In the short period that I've been trying to start off as a professional songwriter, I've realized that songwriting is not just a skill, but a craft that has so many technicalities, so many sets of rules and boundaries. I think that songwriting should be kept apart from the production proces. Especially when producers create the complete instrumental first and try to force melody and lyrics into it. Same kinda thing with musicians. I know that some guitarist would start off from a riff and try to force melody into it. By doing that, they're just laking it way harder, in my opinion.
What do you guys think?
