I f you are like most people today, you have a music or song library on your phone or computer of hundreds or thousands of songs. In fact is not uncommon to see music libraries of tens of thousands of songs.
Your collection of music has likely been assembled over many years, from CD you have ripped, songs that you have downloaded at no cost, songs that you have purchased, songs that a friend or family member has sent to you, and myriad other sources. Moreover, you have likely transferred this library from one machine to another as well as to your phone or several different phones over the years.
With all of these changes and activity it is quite likely that your music library has become disorganized. It may be missing album thumbnails, album names, or even have incorrect song names. You likely have duplicate songs, songs in a multitude of file formats, and songs with different volume levels.
