I have several beefs with iTunes. I have our main library on our iMac...

1) They change their thrice-damned interface seemingly every time I update.
2) Videos (specifically, DVD rips) get automatically added as "Home Movies", making them invisible to my AppleTVs.
3) "Homesharing" requires you to log into Apple. 'Nuff said.
4) Inexplicably slow connections to my AppleTVs. Sometimes no connection at all, requiring a restart of iTunes.
5) Absolutely horrible performance connecting with my Win8 laptop to the library.

That said, I've never seen iTunes delete anything without my explicit say-so. Also, Google's little daemon that uploads my iTunes music library to my Google Play library is a definite plus. So I buy music on Amazon, dump it into iTunes, and listen to it on my cellphone and work computer using Google Play.
