It's the third time i got this bug and it makes me want to burn everything around me. I'm using Beta 3 on my iPod 5, and its the third time when i connect my iPod to a PC that does not have my musics, it just erase all musics! No confirmation, nothing. I set 'manual sync' on iPod, and it stills syncs with 'the' PC. I go my father house today , and i just plugged my iPod into his notebook and started playing some music from my iPod. But it happened again as the first time i did this. And the most annoying is that the iPod still recognizes all my music. It just cant play (gives the error circle) and on the iTunes, it shows no music on the ''coloured bar'' , but when i disable or enable whatever thing on the iPod options, the blue bar grows showing that there is music on the iPod. It's just.... Completely annoying.
