Cannot delete the songs on mp3
I do mine through Windows Media Player
1)Plug in Sansa
2)Open up Windows Media Player and wait for the Sansa e250 icon to show up under the library. First time, might say 'What device is this' or 'Autoplay'-for autoplay,you click 'sync media files to Sansa e250 using WIndows Media Player'
3)When library shows, click 'Sync' if it is not already there.
4)Just simply click and drag the songs you want from the computer library to the list pane on the side.
5)Once your done, click 'Sart sync'
2)Wait for the icon under Library in WIndows Media Player
3)Go to Songs under Sansa e250
4)Right click desired songs and choose Delete. You only want to delete from Sansa e250-nothing else
