Why do I now have to pay 10.99 per month to listen to the same songs I bought on iTunes over ten years ago?

I screwed up. I had my playlist of specific songs, in a specific order, that I would listen to when I did my power walks. I seldom, if ever, made any changes to that playlist. Yesterday, I decided to make a small change, but because I don't do it regularly, I wound up deleting some of the songs on the playlist. No big deal, I thought. I bought those songs on iTunes. It shouldn't take a lot to figure out how to get them back on the playlist. To my huge dismay and disappointment, I found the only way I could access the songs I already bought was by signing up for the Apple Music subscription for $10.99 a month. That's right, $131.88 a year. Corporate Greed at it's finest. How much you want to bet me it doesn't go up to $11.99 next year, then $12.99 the year after, and so forth. Before we know it, I'll be paying $19.99 at month to listen to the same **** songs. I just want my beloved playlist back so I can get on with my power walks. What's going on here?
