does this speed up media player indexing ?

My main problem is the slownesss of navigating thru 15gb of music in the multimedia player :

the "album" page is unusable (too laggy , too many) ,
the search is too slow : I have to wait 5 secondes for the screen to load up the albums ( the small rectangular at the right of the screen becomes smaller as the list extends) them make a search.
If I tap on "show album' and immediatly type a search , nothing comes up.

Finally I only use playlists and "shuffle all".

I also get many errors "impossible to read the file" (in french).

what to do ??
