Some time ago I saw that Youtube had some sort of play-next playlist. Don't know if it was from youtube or some custom made plugin.
I am talking about something like: Bar on bottom of the Youtube web page. You can search videos without stopping the music and then just drag the videos to the bottom in order you want to be played. You enqueue the videos like in Winamp.
For some reason my htc one sv doesnt play stream videos, like youtube vine facebook etc it works fine with wifi tho, pandora doesnt work too but sometimes it does. Its a boost mobile btw. Any one can help me ?
