Solution to 4: Hart House

    The audio file contains snippets of four songs:

    

    1. Sweet Child O' Mine - Guns N' Roses

    2. Savory - Jawbox

    3. Old Salty Dog Blues - Flatt & Scruggs

    4. Sour Girl - Stone Temple Pilots

    

    Each song title contains one of the five tastes. The answer is the missing taste: bitter.

    

    (Note: "Savory" is a truly awful song, and we apologize for making you listen to it. Unfortunately, there weren't a lot of choices.)

BITTER
