Apple Ipod Music Greyed Out

Can anybody tell me why unexpectedly a lot of the songs on my apple ipod have become greyed out! (i.e. the majority of them have gone a light shade of gray leaving random songs in heavy black script that do remain "playable"!) Nothing happens- i.e. they no longer start playing- when I tap them to play and as far as I know, I haven't changed any of the settings. The main computer has had win 10 added recently but I can't see how that would have made any difference to anything.
