Analyze your process for building your library

And evaluate it.

This could be as simple as:

 

Some points to consider are:

 

 

 

• What are the ways music comes to be on your computer?
• Do you want ALL your music in Scratch LIVE?
• Should you have an evaluation stage for new music before spending time organizing and importing it?
• Do you sometimes get music in incompatible formats or of an unacceptable quality? 
• Consider if your process is complex enough to warrant mapping out on paper, or in a flow chart.
• Periodically re-evalute this process

Once you have an idea about how you should be dealing with your music, you can move on to actually organizing it.
