Q: 'Greyed out' tracks on itunes

The greyed out song are probably unchecked. Uncheck songs are normally excluded from syncing and normal track-to-track playback. Using the Songs or List view Ctrl+click any empty checkbox to tick all of the boxes in the active playlist.

I have got the same problem, but it is very odd, only some songs within albums are greyed out even though they appear to be checked. I think this is happening mostly with music that I originally uploaded from CDs. I have tried unchecking and rechecking the checkboxes in accordance with the advice given but this does not change things. Any ideas? (iMac, Yosemite)
