Hello and welcome to Apple Support Communities Jackal1952,
I see that you're having an issue when trying to access some songs on an album that you purchased. I understand your concern, and I'd be happy to look into this with you.
Let's have you delete the album and then download it again. The article below will provide you with the steps on how to redownload past purchases, if needed.
Redownload apps, music, movies, TV shows, and books
If you go through these steps and the issue remains, respond back with some more details. Which device are you using? When you say that they are not accessible, do you mean they are grayed out?
Thank you for using Apple Support Communities.
