We heard from many users that they find their MP3 Script to be loading slow.
We have developed the MP3 Script to load fast and what causes you and your website to load slow are one or both of a the two things:
One (and the most common). You had just activated ALL sources.
To understand better what those sources do, try to visualize: When your visitors types in "Bruno Mars" in the text field, the MP3 Script types "Bruno Mars" to the MP3 source. The script then gathers the results from the source and returns the list of songs of Bruno Mars to your website's results page.
