Today a lot of the hard work is done for you. Many people who produce hip hop or electronic music take advatage of pre made loops and beats, so yes people do actually publish tracks based off of pre made sounds and thats ok. The tricky part then comes into mixing it all together and getting it to sound the way you like it or just different from others. Sometimes simplicity just sounds good. For me mixing and mastering is the hard part, but even that is becoming automated with software like iZotope.
Music has almost become like successful No-code, where you can just click everything in without even touching the keyboard. However you need a good understanding of what you want and how its done based on music knowledge to get something complex done. Also you might find transitions a little challenging.
Tastes have changed and the bar seems to be set lower, but still the sound has to be interesting or the appeal will be limited.
I believe that whatever enables you to make music that YOU like to hear is the important part. Forget the audience and make something that makes you feel, evokes your emotions, or just helps you relax. This is your advantage to be able to create something that is tailored to you.
With that said, sometimes its better to put a project aside or listen to it in your car and see how you feel about it then, your opinion may change.
Hope this made sense.
