9. Find the songs you really don’t like
Why keep the tunes you don’t listen to any more on your playlists? The ones which are left unchecked and the ones you don’t care about can be omitted. Make your playlist full of the tunes you listen to on a regular basis, and it’ll be worth the time you spare to get rid of the other tunes.
You can do this by finding the song you don’t listen to and the from the My Music screen, choose Songs from the drop-down list to the right, then right-click on the column headings and select Skips to show the column on screen and then click the new heading to see the tracks you’ve skipped the most.
