The album is remarkably consistent. "Jackson Park Express" may be my new favorite Weird Al song.
I love how "Foil" starts off as a classic food-related Al parody, then suddenly goes in a bizarre direction. "Mission Statement" is a CSNY tribute consisting of hollow corporate jargon - genius. And his Pixies pastiche "First World Problems" is fantastic.
The thing that makes Al endure where other comic musicians don't is that it's clear he sets out to make good music as a priority. He's a clever wordsmith, but there's more at work with him, or he'd be interchangeable with the people who do Youtube one-off parodies. He validates comedy as a legitimate genre of music rather than exclusively the province of novelty or gag songs. This guy can somehow tap authentically into any style of his choosing, and it doesn't hurt that his band, which has been with him from the beginning, is aces.
Fun fact: He apparently considered parodying "Let It Go" from Frozen as "Make It So" about Star Trek: TNG, but someone online beat him to the concept so he scrapped it.
