Hello Grobbot,
We understand you have an interesting issue with a blank spot showing in this album. We have some questions and a suggestion for steps to attempt to help with this. Do you notice this blank space only with this specific artist or album? Or does it show for any other albums you have?
For suggested steps, if this is the only album being impacted, we'd recommend removing the album then redownloading it.
Redownload music - Apple Support
1. Open the iTunes Store app.
- On your iPhone or iPod touch: At the bottom of your screen, tap More , then tap Purchased.
- On your iPad: Tap Purchased.
2. Tap Music. If you use Family Sharing, tap a family member’s name to see music that they purchased.
3. Find the music that you want to redownload, then tap it.
4. Tap the download button next to a song or album.
Let us know how it goes.
Take care.
