It's $25 a year, and also includes iTunes radio (Apple's Spotify/Pandora-like service). I don't have any DRM (dis)enabled tracks anymore, but this link does say it works. Hope this helps. If you wanted to, you could pay the $25 and milk Apple for upgraded or no-DRM versions of your songs without messing up

This is the same for me - some of my songs I can delete and re-download, but they show up again as protected.
