Recurring Apple ID and password pop-up on Mac for iTunes

this is one of the main reasons i use primarily SPOTIFY NOW.... this has been happening to me for years on more than 2 computers... it is really annoying and i am not sure why any one would put up with this these days when there is so many other platforms that do not have this SUPER ANNOYING GLITCH that APPLE does not fix? Why would Apple not take care of this situation? It is surprising to me, but I have just avoided using itunes primarily because of this annoying glitch that for some STRANGE reason is happening to so many other people i see & feels like a "glitch" that has been annoying me for years now.... anyway, just thought i would vent after years of being annoyed by this when i pay for a monthy payment to apple for itunes... maybe i will just stop paying itunes.... i mean why? put up with this? there is Amazon, Spotify, Youtube Music nowadays.... it blows my mind... alright thanks for reading... bye... enjoy your day hopefully one day Apple fixes this annoying issue.
