You2MP3 Player - Watch YouTube videos on screen and listen MP3 audio on background. Switch between Video and Audio automatically. During incoming/outgoing calls the application automatically pauses the video and upon completion of the call the application automatically continues to play the video from the moment it was paused. You no longer need to continue manually each time your smartphone accepts incoming calls. When the application is inactive or locked the sound track starts to play in the background automatically. When the application is active again instead of the audio track the video continues to play automatically.
