I'd probably say "Spiderwebs" is Gwen Stefani/No Doubt's best song, though I have no idea how "The Sweet Escape," which was everywhere for about six months in 2006-07, just fell off the face of the planet, because, it's a magnificent pop song, and one of the catchiest, bounciest musical numbers of the past decade.
But back on the first hand, it's so not.
The best part of this song is the chord structure, because both the verses and prechorus descend in pitch while at the same time ramping you back up to the part where they squeeze Akon to make the big noise come out. Try to walk while one of the verses of "The Sweet Escape" is on, and try to do it without unconsciously adopting the saucy gait of a seductress descending a flight of stairs. This whole song is the best parts of the Von Trapp children or Andre 3000's big number at the end of Idlewild, which is to say that it invokes the best traditions of American musical theater.
And on top of that, we've got lines like "I've been acting like sour milk all on the floor / It's your fault you didn't shut the refrigerator / Maybe that's the reason I've been acting so cold." Truly we live in a golden age of humanity, to behold works of art such as these lyrics.
It's a great line because it works on several levels: the food metaphor, the refrigerator/cold metaphor, and the juxtaposition of sour milk and sweet escape. But beyond that, it's a great line because lines that you have to practice to sing along to because they're so fast and full of consonants are the most fun. (This is best known as the First Law of Chickity China, the Chinese Chicken.)
I'm going to go listen to about 14 other Gwen Stefani/No Doubt songs now, because all sweet things make you crave more.
