The majority of music on my ipad is greyed out and will not play. .

Is the music in an itunes library on your computer? Does it play from there?

Try this first:

Make sure IOS is updated to latest version

Reboot device by pressing both the home button and sleep/wake (power) buttons at the same time for 10-15 seconds until the apple logo appears on the screen, then let go.

If that does not work, then sync to computer.

Try:

- Reset the iOS device. Nothing will be lost

Reset iOS device: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears.

- Unsync all music and resync

- Reset all settings

Go to Settings > General > Reset and tap Reset All Settings.

All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.

- Restore from backup. See:

iOS: How to back up

- Restore to factory settings/new iOS device.
