I can't hear music in my sansa

You can't. Audiobooks are just like music, and the Sansa treats them that way. Think of them as words spoken without music.

Voice recordings are made on the Sansa, when you use it as a digital recorder. You can record lectures, meetings, or notes to yourself, and play them back.

Format the in the explorer

On your Sansa Fuze, go to the "Settings" menu, then go to "System Settings", then go to "USB Mode", then select "MSC".

Now, connect it to your computer, then double-click "My Computer" on your computer's desktop to run Windows Explorer. You should see your Sansa Fuze show up as "SANSA FUZE". Double click on "SANSA FUZE", and you should see a folder called "MUSIC". Copy your music into that folder. When done, unplug your Fuze and your music will be on it.

check if you have a virus get firmware updates

try holding the power slide/ button type thing in the on position until it turns off, then try turning it back on...

Try to download new Firmware.

The Sansa doesn't play music through the USB port. You can connect the Sansa to your stereo via the Sansa's headphone jack.
