What does the Value field means?

The Value field in search results page give you an indication of the importance of a song, based on the overall views performed in the last quarter ( $ - $$$$$).

This information is meant to guide you in prioritizing your claiming action.

Please note that this is only a graphical symbol; the more songs you claim, the more you will be paid out. Also, if you collect only for a percentage of the considered song, you will be accounted accordingly.
