A song co-arranged (and co-performed - check the drummer in this video) by Steven Drozd of the Flaming Lips? How is this a Wicked Guilty Pleasure?
Because it is primarily written and performed by Steve Burns, who at one time was best known for wearing a green striped shirt, hanging around with a blue puppy and being oblivious to the paw prints around him. Yes, THAT Steve Burns, long rumored to be dead (he never was), victim of male pattern baldness, and.... musician.
Surprisingly, he isn't singing about the mail never failing. He's singing about adult themes, with adult arrangements to his music. Clearly, there is a Flaming Lips influence to the music - several of them are involved with this album, including Drozd and Michael Ivins. But it's not the Lips - it's Steve Burns, and he found a voice all his own - a voice with a reasonably hard rock edge and an awful lot of emotion. I hope you enjoy it and seek out his album, Songs for Dustmites. It deserves more attention than it got, because it is fantastic.
For those not familiar, here is Steve performing his best-known song from 'Blue's Clues". I did use this song as my "You've Got Mail" sound for many years.
