I cannot put my own music when i make a picture play in Pictures

Hello RedHead_GBG,

Thank you for reaching out in Apple Support Communities. Are the songs that's grayed out added from the Apple Music catalog? Do you have an active subscription with Apple Music? If so, you may notice that it'll say, "No Longer Available" next to a song that's grayed out. This would indicate that the song was removed from Apple Music. This information is outlined here:

If a song is grayed out

If you see No Longer Available next to a song that's grayed out, the song was added from Apple Music and was removed from the Apple Music catalog.

This may explain why the songs are grayed out and is outlined here: If songs are missing from your music library after you turn on Sync Library - Apple Support

Kind regards.
