title: Fix music player through the navigation
body: <p>I'm creating the website of a music band. The band would like to have a music player that remains fixed while you browse the pages, a common problem.</p>
  
  <p>Before you realize I wanted to know which technique is best is:
  - Use ajax calls to update the content but keep the player fixed
  - Use the system with the frames, so hated?</p>
  
  <p>you would use that technique for a good SEO ranking?</p>
