Duplicates

There are many reasons why there will be duplicates:

• you have the original albums and “The best of…”
• the same composition performed by different musicians
• the same song by the same group but one is a live performance
• errors in the tagging resulting in different parts of a composition has the same name
• etc.

You can make a Smartlist to detect duplicates.

A simple one is using Name, all the songs with the same name.
Sort them by Name to get the duplicates grouped.

If you use the name (title) only, you can get a lot of false positives especially in case of classical music.

Adding the artist solves this problem.

Adding duration gives you a list of exact duplicates.
