Having owned a Studio V for not quite a month, I've learned that clean tags with all album art removed (from the tags
and the folders) really makes the UI much less annoying, and I unequivocally second Mp3tag (newest vesion 2.50, homepage:
http://www.mp3tag.de/en/) as an excellent freeware solution for all tagging needs. Also, Resource Manager, while still quite lacking, is presently the most efficient way to navigate that I've found. Finally, for what it's worth, I tested a fully charged battery by repeating a folder containing 117 mp3 files at V0 (~245 kbps) at volume level 13 with Screen Off set to Off (a double negative meaning that the screen was always on), and acheived 37+ hours of playback. Unfortunately, the firmware is such that the tracks played in the order 1,2,3,4,5,6,7,8,9,10, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 11, 110, 111, ..., you get the idea, but the battery life is stellar.
