I want to move the BPM numbers only to the BPM field from the file title tag.

I know that \s((.*)) will remove all inside and the parentheses also.

I can't seem to figure out how to search within and only move the numerical data to the bpm field without the text. Since one file has 3 digits and the other 2, I'm not sure how to do this.

Below are two examples:

Horse & Carriage (feat. Mase) (100 bpm)

Woo Hah! (96 bpm)

Can someone help me figure out how to do this?

Thanks!
