My library of songs under my iPhone device are all light grey and won't play?

Hello ejf1023,

Thanks for using the Apple Support Communities!

Are you using Apple Music?

Do you sync your music to your iPhone using iTunes?

Check out these articles and try the steps provided on your iPhone:

If songs are missing from your music library after you turn on Sync Library

Sync your iPhone, iPad, or iPod using iTunes on your computer

Kindest Regards.
