How come I can't listen to music from YouTube with my iPhone on the lock screen so off?

I use to always now it just disappears when I hit the play button on the lock screen it'll disappear?

You actually can. Once you lock your screen, use your finger to open the control center. Swipe over to music and press play.

  • Why can't i play youtube videos in background/lock screen on my iphone anymore? I always used to be able to do this, is there any way to still do it? Or is there any way to get an older version of the app that will alow me to do it? And does anyone know why they stopped this function? Very frustrating!

  • What's a good free music downloader that I can listen to my music offline? Okay, I have looked EVERYWHERE for an app like this. I have a new iPhone and I can't find a simple app that lets me download music and then play it when I have no internet. All I need is an app where you can download songs or videos from YouTube or something on the Wi-Fi, but then when you're off Wi-Fi you can still listen to the music. All the apps I've tried don't work or I can't find them, please help
  • My iphone lags when I watch youtube, skips couple seconds while i listen to music? Ok so I don't know why but since I got the new ios 7 update, my iphone started to play funny. The other day I was playing music and I noticed that it was skipping seconds in a song in like 1/5 songs. Today on netflix and youtube, my phone starts to lag when I open either youtube or netflix. Like the video needs time so it goes back to normal. I don't know if it's the update that I should be worried about or my iphone. Btw it's an iphone 4.
