Hi KarterJK,
Thank you for using Microsoft Windows forum.
IF you want to Listen to multiple songs or want to watch multiple vidoes without having to manually select one by one after each song or video is finished, you may select the songs or the vidoes you want to play, then right click and add to Windows Media player list, that way you do not have to bother about selecting a song or a video after the last song or video has finished playing.
And with reference to launching Windows Media Player 13. We do not have the information on it yet.
If you have any feedback for us you may click Windows 7 feedback
