Adding Music Tracks to Your Sansa MP3 Player Using Napster

[gutchman84]

one time i added songs to our Sansa e280 player then removed the player from the USB port, but then I accidentally inserted the USB charger back in while the player was writing the songs to the list. The screen faded out and I fixed it, but ShopSansa, does this ruin the battery life of the player or the player itself in any way?
