25. Issue regarding incomplete display on X1 2nd gen(after updated media library)

A: So far, the maximum number of songs that can be added to X1 2nd gen's media library is about 30,000. That's to say, after updating the media library, there will be only 30,000 songs at top showed on X1II even though there are more than 30,000 songs in your Micro SD card.  Large quantity of songs would create massive databases which would occupy too much internal memory of X1 2nd gen, and might cause instability or even failure to X1 2nd gen's system.  For system stability, we limited the updated track number on X1 2nd gen. 
We also limited the internal playlist number to 100 for similar reason.

PS: No track number limit while viewing or playing tracks via "Browse files".
