try to let the battery run out then fully recharge it then play songs if any more prlblems happen let me know

soak unit it rubbing alcohol if dropped in water(water has deposits when dry that short stuuf out alcohol cleans and leaves no residue)let soak for a few hours(make sure battery is out)then shake out excess alcohol and let dry for a day in warm dry area.clean contacts on battery with alcohol ans qtips and reinstall battery then try to charge-same thing happened to me tried this and worked fine hopefully didnt short chips!!!!!Best of Luck to you!!!use 90% rubbing alcohol!!!let me know if worked!!!

first wat i would do is recharge it again and see wat happens

It sounds like you are having some firmware issue...Try to update the firmware..Once you do so..i am sure the problem will go away
Thank you

i have the same problem, samsung froze at its logo, cannot be recognized by my computer. the problem occured when i try to make my mp3 as a usb boot driver. i cannot turn off it unless reset it. 

Take batteries out and let reset. Give aleast 1 hour

Have never worked on this model but on any other make you would be at main board replacement stage I'm afraid,.Sounds like microprocesser ,eprom fault.Sorry but not cheap fix by the sounds of things,how old is unit,any chance is under guarantee.You could try bringing it back to where you bought it,.

Use a paperclip to reset the system

Try taking a toothpick, and at the bottom of your mp3 player, there is the usb insert port thing, but then there is this little hole to the right...it's the reset button. After you hit the reset button, just let it charge.

Sounds like it may be the index in your Music Library. Try going into Recovery Mode; remove battery, hold power switch to ON, replace battery, release power switch when the Recovery Mode screen appears on the screen. Run Option 1 CleanUP, after it completes run Option 4 Restart. You will get a Rebuilding Library screen when it reboots, that's normal, then it should go back to your startup screen. Good luck and let us know what happened
