Having 2 issues with iTunes and iPod touch
So I'm having 2 issues with iTunes and my iPod Touch.
First Issue: I have 2 albums that are AAC format and I can't for the life of me figure out how to add them to iTunes. I checked online and found something to do with import settings changing it to MP3 but it doesn't work for me at all. I click "Add to library" than the songs I want to add (the AAC ones) and than nothing happens... no pop ups, no songs are added... nothing. How do I fix this?
Second: I hate my iPod Touch right now. It won't sync all my songs, it will sync a few in an album but not all of them. Some songs that are there at one point are than gone from the ipod a few hours later for no reason. I've tried syncing over wi-fi and nothing works. It's like a crap-shoot as to what gets synced and what gets un-synched. I've got like 20 gb's free still on it... Please help me in any of these areas!
I've got the latest version of iTunes on my Macbook Pro and a 64gb iPod Touch that's also up to date.
iPod touch, iOS 9.2
