A way to remove mixes with crowd noise from search

Hi,

I don't think there is a effective way to search for only mixes with no crowd noise. E.g . Even the "Dj Master quality" search tag shows results that have "live" in the title. Some of which have crowd noise and some which don't.

Adding a "crowd noise" tag to uploads and then having a "no crowd noise" search tag would be a good way to implement this?.

This.
