TheBigCore: 1) Download, extract / install, and open Audacious Media Player.

2) Drag the individual .AUD files from your LSL7 GOG installation’s MUSIC folder into Audacious’ playlist editor.

3) Highlight the audio track you want to play and double-click it. Alternatively, you can press the play icon or the letter x on your keyboard to listen to the highlighted track.

On a related note, the Leisure Suit Larry 7 theme is the file 13000.AUD. It’s a really swingin’ track.

seinmind: Frank Zottoli composed that game's score and the whole album is a great listen. A moment in time when a video game soundtrack had actual musicians playing with instruments. Thanks for the information.
