Another "LIVID" user here. I have over 100 gigs of music and my main folder is YEARS worth of carefully ripped, named and cataloged MP3s.
I never had one issue until I started trying to put music in my iPad several years ago. At one point, I "let" itunes "keep my music organized" which completely redid my file system. Several other times, whole CD's have been deleted. (I don't use AVG). I have had at least 5 times that itunes delete all the music off my ipad, only it really didn't because all the memory was used but not tunes showed up. Multiple other issues, and several times spent HOURS rebuilding the library, or hours and hours reloading it to ipad.
So last week I had tones of old stuff in my recycle bin and I emptied it for the first time in months. Now I notice today, that song #1 is missing from every album I've checked. Several of them are missing song #2 as well, but ALL of them are missing the first song. In my primary music folder there are over 700 ripped CDs of MY music. And EVERY SINGLE ONE OF THEM (sorry for yelling, but I can't punch somebody!) is gone. Every album starts with the second song. This means why whole catalog of music is ruined now and every single CD has to be redone to add the first song back in.
Last week was the last time my whole music catalog got wiped off the ipad and I was fuming at the prospect of once again spending hours redoing it. But this.... this is FAR worse. I already put an iPod and a iPad Mini Retina on my Christmas list for this year. Not only are both coming off, but I'll never buy another product from Apple as long as I live. The almighty "we are better" thing is cool if everything IS better but this software has sucked completely in every version on an otherwise perfectly running and clean Windows 7 machine. It even deleted a just recorded original song I did myself and it wasn't backed up yet since it was just completed!
Delete music off my ipad and hours spent rebuilding it = a waste of my time. Deleting it off my hard drive, when some of it is lost, some CD's sold, or from no longer playable CDs...That music is lost for good! . COMPLETELY INTOLERABLE! I'm out.
