how will xplorerme work with lots of music tracks

I am interested to know how XplorerME (new version) would deal with lots of music tracks loaded (Im talking loads off memory card - 3000+), does too many tunes affect playback or navigation?

I am also interested to know if there is an 'auto update library' feature for new tracks added (eg. just added to my memory card), whether this feature can be enabled to 'auto update the library' on app startup? Is there room for a request for this if the feature is not there

there isnt a music libary in XploreME (yet)
you are choosing track from files.

How do you mean just like a regular file list - so there is no display organising - Artists, Albums, Tracks...
