I remember reading an article where tommy motola recently said that michael has left more songs in his vaults than elvis and at work my friend who is older than me and a fan of bob marley said he believes that michael's songs will be released all the time slowly he also said that new songs from elvis, Marley and Hendrix's are released every year, motola said in the article michael has left a lot more songs than elvis did and they could go on for many years.
This gives me hope that michael has not really left us.
