Dear Spotify Community

I have been the using Spotify for a couple of months on my Android phone (HTC Wildfire S) without problem
Over the last week I have been experiencing sound problems with downloaded playlists. The content is uneven or stutters. It does this on all tracks most of the time. The play bar is unaffected and indicates that the track is playing correctly.
I have reinstalled spotify a number of times and redo loaded the playlists
I have tried listening with and without headphones and the sound quality is still uneven and stuttered
I have listened to other media through the phone with no issue
The playlist work fine on my ipad device, it is a problem localised to the Android device

If anyone has any ideas to solve this problem I would be most grateful

Charles
