When I plugged it in it started swinging but wouldn't play music then it stopped and wont start up again what do I do?

You can clean the lens with a small amount of windex and put a little oil like 3 and 1 oil on the spindle motor shaft and on the sled rails. Good luck !

Sounds like a short n wiring. Was it plugged into wall outlet or running on batteries? Did u smell any burning? Or like warm, hot plastic? If it's ran on batteries or if it is a .wall plug, but there was no smell. U might b able to open it up and locate a lose, disconnected or old and or fauly wire. Which u could reconnect if still good. If faulty, then splice, replace, reconnect.That would b, if lucky. If your not and or it was a short, then it's likely to have burned up the motor, which is more likely if it was a wall plug.

Where do you plug in the phones? if it is an iPhone. the music playing will be stopped, just to precent your ears to be damaged. When plugging in headphones, while the volume is high, the sound level can be so high, you can damage your ears. Yes damage that will last the set of your life, because loss of hearing, can't regenerate. For that reason some MP3 played, cill stop music playing, as soon as a headphone is plugged in.
Just start the music that was playing when you did lower he output volume if the music stops.
