All music subscription such as napster and rhapsody requires you to sync your device every single month.The reason is to prevent customer from cancelling their music subscription..once you cancel your membership all the songs you have on your device will become useless.In another word, you are renting the music...I dont know if you are asking how to to remove all the songs from your device..but if thats the case you can do that in 3 different ways you can do that..you can format your device..that options will completely remove all the songs from your device..and to do that you can open up your windows media player ...assuming that you have version 11..click on sync and your device will be listed and click format..
The seconds option ,you have to make sure that the device is on MSC mode...then make sure your device is plug in to the computer
..Then go to programs - accesories - windows explorer, find the SanDisk in my computer
, go to media
and delete them from there.
Either under sync
panel in your windows media
player it will show your music when it's connected. just click the plus signs for what song you need to get rid of, right click and click delete.Hope
P.S.Please rate accordingly...
