I tried the reinstall, but no joy. Thanks for the answer though
The problem is since then things have escalated to the point where my library is 10GB smaller than it used to be, and I've realised that the problem is not confined to songs on the nano.
I'm a person who likes real CDs, so at least I have full back up potentially, though it will mean taking some boxes out of the garage and chasing up people I loaned CDs to.
But it's so random - why would some songs go missing and not others - it's not limited to one album for example, sometimes an entire album will go missing and at other times it will be one song from an album.
Is there any messy software that could be causing this? I use legit versions of Photoshop etc (as my credit card still reminds me), I use a lot of legit shareware programs such as those featured on MacZot. I have again a legit copy of
Tidy Up, and the freeware/donationware
Senuti. I haven't run Tidy Up in months though - I thought that may have been the culprit through some mis-click of my own.
If you made it this far down the page, thank you! I'm a bit blearly eyed with tiredness so I hope it makes sense. Any suggestions would be most welcome.
PS the songs that are 'empty' tracks are deleted from the HD, not just from the iTunes library.
