the music thing is rough because everyone and their dog is uploading ai tracks now, so youre competing against millions of the same stuff. saturation kills it before you even start.
honestly the better play is being the guy who knows the tools in a place where most people dont. like there are tons of small local businesses (restaurants, real estate guys, gyms) who keep hearing "use AI" but have no clue how. you set up their content, basic chatbot, listing photos cleaned up, whatever... charge monthly. they dont care its AI, they care their stuff looks better and they save time.
the content-selling route mostly dies cause the output isnt the value anymore, anyone can press generate. the value is knowing what to generate and for who.
start with one niche you actually understand a bit, build like 2-3 results, then use those to get more. way less random than spraying music everywhere and hoping the algo picks you.
