+ <description>
+  <p>
+Think of Spotify as your new music collection. Your library. Only this time
+your collection is vast: millions of tracks and counting.  Spotify comes in
+all shapes and sizes, available for your PC, Mac, home audio system and
+mobile phone. Wherever you go, your music follows you. And because the music
+plays live, there’s no need to wait for downloads and no big dent in your
+hard drive. 
+  </p>
+  <p>
+There are are two ways to listen to spotify using linux: Using the web-based
+service or using this native client.
