My question is     I have had a FREE account for many years  and a playlist of songs 

the free versions playlist  will be a lower resolution/ fidelity as well I assume 

if I decide to subscribe to PREMIUM. With higher resolution/fidelity  can anyone advise regarding the existing playlist I have     What resolution fidelity on playback will I have ???  The same as now or will thru DEEZER  Magic.      Will all my playback lists     OLD a& NEW  be at the higher resolution???       Thanks everyone.
