I am retired as well. This is great, I have much more time to listen to music.
Following up on @tksteingraber.
I was able to bring up my streaming to the level of my vinyl sound quality. The benefits have been simply overwhelming for $12.99 per month. I have access to essentially all music. There is over half a million albums at high resolution, this is completely opened up by scope of music. Not to mention as your knees get more creaky you don’t have to get up enough or risk breaking off a stylist.
You might consider saving up and slowly investing in streaming. I have found you can spread out the payments over six months to years and the benefits are huge just a thought from my experience.. now retired for five years.
