How do I unlock all my old iTunes songs?

I have a lot of iTunes songs from the 2005-2010 era that are all drm’d and can’t be played with anything but my iTunes logged into my account I purchased them with.

It’s 2023, I hate iTunes, but I can’t play half of my library. Does anyone have any idea what I can do? There are paid tools that claim to be able to do it but I’m not convinced…
