I have been using nokia 5300 for past 12 months. Now i got a problem in music player. Problem is whenever i refresh music library only 137 songs are get dispalyed(i stored nearly 400 songs of .M4A format in card!!!). I formatted and checked with other memory card also. I upgraded the firmware version n i did restore factory also...But i got the same problem.It was working fine until i created and deleted a playlist(contains 137 songs).Can anyone guess what the problem is and what i suppose to do..
