Rhapsody question

[Bgranger]

I have a playlist of my favorite songs of my rhapsody library downloaded to my phone. lets say for example the playlist has 80 songs in it currently and all are downloaded to the phone, I open the rhapsody program on my pc and edit the playlist by adding a song to it now making it 81 songs. but even after restarting my phone and opening the rhapsody app it still will show the playlist to have 80 songs, even though when i open the playlist it has the new song at the end and I can count out 81 songs. and the only way I can get the new song downloaded or even added to the total song count of the playlist is to clear all downloads and download the whole playlist again.

so essentially my question is. How do you make a rhapsody playlist automatically update and download new songs onto your phone.
