What device is it exactly. Ipods are different than other devices.
There is probably an option to delete music that you are listening to in the menu system of your device. But the easiest way to remove a lot of songs at once is to plug the device into your computer with the appropriate cord. Your computer will detect the connection (just like when you want to add songs) and it may present a screen of choices. Choose the folder icon, which will let you explore the device. Find the songs you want to delete, click them and hit delete.
That's a pretty generalized answer...to give specifics, I'd need to know your operating system (windows 7, Windows XP, Windows Vista, Mac, etc) and the make and model of your mp3 player.

Hello,

Transfers onto the m240 can be done in 2 USB connection modes:
MTP mode: Media Transfer Protocol using software, e.g. Windows Media Player 10 or higher.
MSC mode: Mass Storage Class using Windows Explorer, looking in "My Computer" viewing the player as a removable disk.

Typically, songs put onto the player in MSC mode can not be viewed in MTP mode and the other way around.

Switching to MSC mode in the player's menu:
Look in the player under Settings Menus > USB > select MSC for using the "copy and paste" or "drag and drop" method for transfers in "My Computer".
When Auto Detect is selected, it depends on the configuration of the computer, what setup for priority has been installed.

Forcing the player into MSC mode:
1. Turn device OFF.
2. Facing the hold switch slide it to the right so an orange color would show putting the device on Hold.
3. Connect the device to the PC.

Information for the USB connection mode and how to make hidden files in XP and Vista visible, on the support site:

To remove and add songs on this player, you can simply connect it to a computer via USB cable and when its detected already you can now remove and add songs from it...

I went to device manager and uninstall the device. Then went into Add hardware and reinstall the device and it worked.

I can not add or remove any songs in my mp3, the device is not detected by my computer. My mp3 is maestro force (spectra). Please answered.

You should be able to hook your mp3 player up to your computer with the USB cable. This will allow you to browser the directory where the songs are and delete or add new songs. Your mp3 player will appear in your computer as a removable disk. The songs that you put on your mp3 player need to be in mp3 or wma format. I also found the instruction manual for your product in pdf format. http://www.gpx.com/shop_ind.php?id=%20%20344#
