Reads files not properly a

I would like to use the player, yes, but unlike eg MortPlayer there is no way at program activation re-read the audio files (specific folder). When I recorded new music it often takes 24 hours or even longer, until he finds them. Equally bad if I choose a file in a file manager and then want to run with Jet Audio, it can not also, if it does not have the file in its index.

Is it so hard for Android programs sometimes directly access the directories and not always to create an image only every x-hours? There are even files displayed that have long since deleted.
