See this site. He has very interesting thoughts about the current state of record labels left and right pushing material done by semi-musicians, causing an overflow of material, and other thoughts how to grow as musicians.
I kind of agree with the idea of musicians/composers always having a need to learn more about music, how to compose, what has been done in the past.
It’s for example very good to listen to other music than just electronic dance music, even if you are an EDM producer.
Writers write, programmers program, composers compose. It’s a constant progress. Just doing quick stuff material and hoping it sells might or might not work, but in the long term it’s much better to really work on the craft. Even Mozart’s first compositions were somewhat naive, but he progressed super-fast.
