Almost every media player has a music library. This is just like a normal library where you store books, except that you’re storing music. The music library is a great way to catalog your music collection. What makes it most convenient is that it allows you to locate and play files with a simple search. You can conduct a music library search by album, song, or artist name, genre, rating, and year. You can even rate the songs yourself. So say, for instance, you want to listen to all the songs that you’ve rated five stars, you simply search accordingly and select the ‘play all’ option. You can even customize a playlist and save it in your music library.
