5 hours later and I am at 2700 of 3300 uploaded. So, It doesn't take that long. When it is done I can just download the songs I want to listen to when I don't have a wifi connection.Upload them to google play music or Amazon. Takes forever depending on how many you have (I did it with 6000+ songs)
Then you can stream your entire library & /or download favorites for offline listening.
