1. Open OpenIv (make sure you have 2.6.4 to edit audio files!)
2. In your gtav directory, head to /x64/audio/sfx/SCRIPT.rpf/offmission_wasted.awc
3. Right click offmission_wasted.awc and select "Export to OpenFormats(.oac)."
4. Select any folder (I recommend Desktop) and click "open folder"
5. Head to the destination you selected and locate files called "offmission_wasted.oac" and an "offmission_wasted" folder.
6  BACKUP 0x0465EDA9 (optional, because I included backup) 
7. Drag the file I included in the "THE OLD MUSIC" folder into the "offmission_wasted" folder.
8. Make sure you select "Copy and Replace"!!!!! (or REplace)
9. After replacing the file, check it to make sure it's the violin music.
10.Head back to OpenIV and drag the "offmission_wasted.oac" file into the destination of the offmission_wasted.awc file (Script.rpf)
11.If you did it correctly, OpenFormats will open and you press ok.
12.THAT SHOULD BE IT!!! If there are ANY errors, write a comment to the file on gtav mods and I wil help out!

MAKE SURE EDIT MODE IS ON!

ENJOYYY!!!!!
