I don't know what the problem is in general, but FOR ME it's definitely too much flexibility and choice vs. limited time (on Earth, and also during the day). Every modern DAW nowadays - well, maybe except Reaper? - has enough: sounds, instruments, effects, tools and workflows that one can do almost any type of music, for as long as they live. Literally. But then you have other DAWs, plugins, hardware gear, monitoring equipment, room treatment solutions, tutorials, forums, etc... taking the precious time and attention.
All of the above are for me ME manage.
I now removed all other DAWs from my computer, disabled plugins in Reason, have one controller hooked up, uninstalled all social media from my phone, ordered a Kindle to start reading - actual stuff worth reading - more, will offend some mods & users here to get banned for good, soon(ish)
In general, though?
The way music is now produced, distributed and marketed also puts lots of people in a very narrow stylistic niches in artistic and technical terms, which makes the tracks difficult to distinguish and anyone sounding differently is viewed as sounding "wrong". Short attention spans promote the music that's immediately catchy and simple / easily accessible, "obnoxiously" grabbing the attention that's rarely lasting and memorable. Production values greatly overshadow artistic qualities - the DAWs make the "cutting-edge" techniques like parallel-processing, side-chaining, saturation, multiband compression, dynamic EQing, limiting, maximization, etc. easily accessible to everyone, but since nowadays a musician is their producer, mixing & mastering engineer, a manager, a PR person, an IT tech, a graphic designer, a lawyer, etc. - there's not enough time left for the actual music. And you have to produce fast, pump the stuff out often, so that your "audience" doesn't lose interest and that you could build that "passive income" library...
Obviously, there's lots of awesome music out there, still!
It's just more difficult to find in the sea of highly-polished, formulaic and soulless "shit".
