Whatever works, but music, or the music the algorithm provides for you, being permanently played out after a few months, does indicate the algorithm is not providing you with music of any depth.

People used to listen to albums for many years, or longer. I still listen to music I grew up with my parents listening to.

Like I said that's cool if it works for you - great, but I think you might be missing out on depth. I would say this is a big check mark against streaming services. It might be that many people now consuming music this way are not really getting the music listening experience they would have pre-streaming services. (Don't get me wrong there have always been people who never really had that deep a connection to music, and just listened to whatever was in the charts at the time.)
