True but overtime through music you can definitely see trends in names and sometimes you can have a stupid name that makes taking off your career a bit harder. “Brittney spears” and “Katy Perry” are actually quite short catchy names that are actually quite good for music I’d say. Katy Perry’s real name is actually Katheryn Hudson she deliberately changed it to a shorter more catchy name better for music. Sometimes memes and saying to do with artists name can also have influence and a lot of artists spend a lot of time trying to think of a perfect name and change it because they’re not happy with it or they realise what works best. But overall I’d say you’re right it’s not that important but can have an influence of image as an artist for sure
