Many, perhaps most, music services have towards the bottom of an artist page a list of similar artists that you can explore. Also, if you see what compilations a song, or an artist, is on you can see what else is on that collection.
Also, music services have collections for different styles of music. As you listen to those, if you like a song you can try to see if you like other songs from the same group / artist.
I can’t even think of any valid reason why Udemy would need GenAI. Closed my account. This is the type of behavior I will not accept from a company. If enough people stood up to the Reddit’s and Udemy’s of the world they may, … maybe, be more responsible towards their users and their partners (in this case the people posting courses in Udemy).
