I have a Nexus S currently running 4.0.4 Ice Cream Sandwich, which i have been pretty satisfied with until now. I transfer my music from my mac to my nexus s by dragging the file straight from iTunes to the MUSIC folder in the USB storage of my phone (titled NEXUS S in finder). It has been working well, but now the new music I dragged from my computer to my phone shows up on the storage of my phone ON THE COMPUTER but not on the music or double twist app itself. A weird thing i noticed is that if my have my USB storage turned on, i usually cannot access Doubletwist/music app but now i can. Also, my phone takes really long and basically doesn't disconnect from my computer unless i eject on the mac itself. I'm also kind of scared to do a factory reset, as some of you might suggest, because I don't want to lose all my data/music/apps/pictures .. etc. Please help!
