I am new to the Droid phones. I left the iphone4 to switch. What ids the best music app that allows me to down load my music to my phone from my computer to carry with me like I did with my iphone. I have tried a couple but they seem to play one song and get stuck. I now have the power amp but I can't figure out how to down load the music to the phone or even if it is supposed to down load the music to the phone. Playing the music through the phone from my computer doesn't make sense because I want the music to take with me. Besides I have a good set of blue tooth head phones that do that. Can anyone help out this novice.
