You Can embed songs directly from youtube, if you click on the share tab in youtube , then click on embed tab when the box opens up and copy the code, then click on profile in your social centre home, then click on personality, I scrolled down to music and pasted the code, save the settings and you should have a song on your profile, view your profile press play and you have music, hope this helps
the code from youtube you copied should look like this one below
