If it makes it any better, the up slider makes use of WidgetLocker's "toggle interactions" feature, so I can actually disable being able to click on widgets, and then enable it by powering on the screen, swiping up, then toggling things as necessary.

I use SyncBack to sync my music to my phone (and to my flash drive as well). Make a profile for my music folder, copy all files matching *.mp3 to Music folder on SD card. Easy.
