I used the layout premade on the layout forum then I had to read the entire code and make edits in the code like where it says background image i changed the url to make my own background. it seems complicated but it is easy. for music i use this site
http://youtubeembedcode.com/en/
i get the youtube url to the song i want and then paste it in the url box on the that website and select auto play and it allows the video to play with out having some one click play on the video.
