My IPhone keeps randomly playing music by itself?

I dropped it about 30mins ago and while answering questions on here, it kept playing Marilyn Manson songs by itself at different speeds without me pressing any buttons and wouldn't stop when I pressed pause until I kept pressing it for ages. After that it has come on and off another three times but it plays music really sped up D: is it broken?

Probably yes

Yes, or if you belive in supernatural paranormal stuff.( i do belive myself: P ) them you may have a type of possession or just a plain old ghost / poltergiest and hey! It may even be a dead someone in relation to marilyn himself! But anyway you should find an apple store near u right away and have someone look at your phone just incase. Hpoe i helped.

It could be, but try restoring it on itunes, it might fix it, if not try putting it into dfu mode.plug it into your computer then hold the power button for 3 seconds, still holding the power hold the home button for 10 seconds, let go of the power button and hold the home button till you hear your computer detect it. Then restore it from apple. DO NOT DO THIS IF YOU'VE JAILBROKEN IT. If none of that works then it probably is yes.
Epic music taste btw: D
Hope I helped

Mine keeps doing that to

HOW DO I STOP MUSIC I DOWNLOADED FROM PLAYING ALL THE TIME AND RUNNING MY BATTERY DOWN?! ALSO EVERYTIME I CHARGE MY PHONE IN CAR, 2014 Ford Edge it starts playing my music!
