Hi all,
I found a solution so thought I would share it with you all to see if you have any successes.
N.B. The iPad will need to be restored to factory settings during this process, so would be a good idea to copy any photos etc. that you have on there to desktop to save losing them.
1. Connect iPad to iTunes (wired connection)
2. Click Restore iPad (not from backup)
3. When iPad has restored go through the set up process
4. When it comes to signing in with your Apple ID - SKIP THIS STEP!!! This is imperative!!
5. After finishing set up, iPad will appear in your iTunes
6. Sync iPad - this should then sync all of your music with no greyed out "Ghost" songs
7. Go into settings and sign in with your Apple ID
8. Sync iPad again
9. Back iPad up to the iCloud
10. Enjoy your as new iPad.
Please let me know if you thought this was helpful.
Thanks
