I just installed power amp onto my new phone and the music 'came over' in a total mess. I have A LOT of music and having to edit all of this is really not much of an option. Since I have never had to put power amp on a new phone before, if I had known all the ins and outs I would have just copied the music over separately. But there was warning or information on how the 'reinstalls' work. This really gripes me!
