maramum: If you are downloading music then look for the highest bit rate possible before selecting. You will see lots at 128 192 and even as low as 98 BPM. The best you can get is 320 BPM and there is a very noticeable difference in the sound quality. If you are fussy like me, you will ignore anything less. the only trouble is that 320 is difficult to find, but it's there. I downloaded some classical last night which sounds fine. I also downloaded some Queen at 192 which sounds terrible. Perhaps we will both get smarter with experience.
I assume that you have overcome the problem you had in getting your downloads to play.
