So basically after downloading from soundcloud I get a list of .mp3 files with format usually like:
songname_number9digits - artist.mp3
Format observations:
1. "songname" some times have other symbols, spaces, etc.
2. "number9digits" the number is randomized is is usually 9 digits
3. "songname" and "number9digits" are seperated by "_" with no spaces in between
4. "number9digits" and "artist" are seperated with " - " (space dash space)
Format I really want:
artist - songname.mp3
I just couldn't get the expression to match and replace for the life of me.
Thanks for the help!
