Hi there porteleanor,
I see this is your first post in the Apple Support Communities, so allow me to welcome you! The issue you describe is that you downloaded an album from Apple Music, and while you can see the individual songs, it doesn't show up when you click on My Music and select Albums under Library. I love organizing my music through iTunes, and I know I'd want to be able to see all the albums as well as the individual songs.
My first recommendation is to check for updates. You can do this by going to Settings > General > Software Update. If there are any updates go ahead and install them. Once the installation is complete, go back to the Music app and check under My Music > Library > and then select Albums from the pull-down menu.
If that doesn't resolve the issue, I'd like you to try another step. Keep in mind that when you sign out of Apple Music and sign back in, it removes any music you've downloaded, however it will redownload it again and hopefully show the album this time.
- Go to Settings > iTunes & App Stores
- Tap on your Apple ID and sign out
- Sign back in
- Check the Music app, go to My Music > Library > and select Albums from the pull-down menu.
Best wishes!
