Just upgraded and noticed something odd. I'm not sure if it was like this in 4.9, but it was more obvious after the upgrade to 5. It "updated" the music library upon first launch and when I was thumbing through my music ALL of my Metallica & Might-Mighty Bosstones were unchecked. Just those 2 bands, but all of their albums. They all played fine and I simply rechecked the boxes. Anyone else notice something similar?
