When your little ray of sunshine has a cloudy day, what better way to lift his or her spirits than with a few catchy ditties from Oscar the Grouch? How could you not love a grumpy monster who croons an ode to the cacophony of city sounds in "Noise" and imagines a perfect land where "you won't see smiles flash and there's great piles of trash" in "Grouchelot"? Though Oscar may delight in maintaining a perpetual bad mood, these quirky tunes, such as "Let a Frown Be Your Umbrella" and "I'm Sad Because I'm Happy," are sure to bring smiles to the most disagreeable of days. --Deborah Moore
