Need help understanding the song Matching tool

In the song Matching tool, do we select the Genere in the far right column or the genere/song listed under the BEAT column?

example 7 nation Army, if I select ROCK, then I can’t find Tango under song.

I;m confused.

The song matching tool is not a tool. It is a collection of songs with a suggestion, what beat you can use for that song with the tempo. Nothing more than that.

You are understanding it correctly. The genre normally is the default library Folder that you would find the beat. However, in this case is appears that it’s not correct. The only Tango I can find is in the World folder, not the Rock folder.
