The song "Love Is an Open Door" from the film "Frozen" is a sweet, romantic duet that exemplifies the best qualities of falling in love ... which is why it's slightly awkward when sung by a single guy. (Emphasis on "single" in both senses.)
The singer in question even playfully writes in the description: "I need a girlfriend." Yeah, you can probably guess where this one is going. Watch above as online singing sensation Matt Mulholland expertly performs the duet ... totally solo.
