I can see that you're using BASS_MP3_SETPOS. This greatly slows down loading 
time as every frame must be read. Tone Skoda posted a message on the BASS 
forum, i see. Ian showed a little trick to make it loook like it's loading 
faster. You can view it over here:

This will probably wrap over, so make sure you get the whole thing.
