Put your ear to the ground and you'll hear it: the pop-storm thunder approach of the "Hannah Montana: Best of Both Worlds" tour, closely followed by the lightning-bright squeals of thousands of preteen girls.

Disney has hit on quite the formula with the goofily feel-good "Hannah" series, which stars Miley Cyrus as a teenage girl who lives a secret life as a beloved pop star.

Cyrus and the Mouse House have scored major wins with anything emblazoned with the "Hannah Montana" name, including the megatour and the two "Hannah" soundtracks, both of which debuted in the top spot on the Billboard Hot 200 chart and together have sold 5.9 million copies, according to Nielsen SoundScan. A set of four tickets for this week's Detroit show was sold on eBay last week for $2,395 -- and the seats weren't even in the first row.

How much longer the "Hannah Montana" obsession will last is anybody's guess, although it will no doubt fade as Cyrus and her fans grow into their driver's license years. (Just ask Justin and Britney whether anyone has bothered them about their "Mickey Mouse Club" stints lately.)

Whatever the projected lifespan of the "Hannah" phenomenon is, there are two things it continues to have going for it: Cyrus' deep-beyond-her-years pipes and the positive message of the "Hannah" songs. In honor of such achievement, here's a look at five sets of "Hannah" lyrics and their deeper meanings.

"BEST OF BOTH WORLDS"

Lyrics: "You go to movie premieres (is that Orlando Bloom?)/Hear your songs on the radio/ Livin' two lives is a little weird/But school's cool 'cause nobody knows/Yeah you get to be a small town girl/But big-time when you play your guitar/ You get the best of both worlds."

Tween Translation: The "Hannah Montana" theme song highlights the oddity of living a double life when our girl is oh-so-normal when not wearing her streaky blonde wig. You could be her friend, or just as easily be her. Depends on your vocal cords, and whether your dad ever rocked a mullet on CMT.

Message for grown-ups: "Lord of the Rings" might be the Oscar-winning, higher-grossing trilogy, but "Pirates of the Caribbean" is what Mr. Bloom is most famous for among the 8-12 set.

"WHO SAID"

Lyrics: "Who said, who said I can't be Superman I say/I say that I know I can/Who said, who said I won't be president/I say, I say you ain't seen nothin' yet."

Tween Translation: Another rah-rah, I-can-do-anything (as opposed to you-can-do-anything) track from the "Hannah Montana" original soundtrack lets kids know that they need not stop at pop star when they could be commander in chief or, better yet, a man of steel.

Message for grown-ups: When Miley follows in Hillary's footsteps in 30 years, your kids are going to want tickets to political fundraisers just as badly as they want "Hannah" tickets now. Don't say you weren't warned.

"WE GOT THE PARTY (WITH US)"

Lyrics: "It's Friday and there's nowhere to be/We're kickin' it together it's so good to be free/We got each other and that's all we need/The rest is up to you and me."

Tween translation: Make your own fun, but only if it's not a school night.

Message for grown-ups: Wouldn't you rather buy your daughter a nice pink "Hannah Montana" backpack than have her watching Jamie Lynn Spears in "Zoey 101"?

"NOBODY'S PERFECT"

Lyrics: "Sometimes I work a scheme/But then it flips on me/Doesn't turn out how I planned get stuck in quicksand/But no problem can't be solved/Once I get involved/I try to be delicate/Then crash right into it/But my intentions are good/Sometimes just misunderstood."

Tween translation: If at first you don't succeed, try, try again.

Message for grown-ups: Your kid is basically good, so cut her some slack when she leaves her bike in the middle of the driveway for the 10th time.

"MAKE SOME NOISE"

Lyrics: "Don't let anyone/Tell you that you're not strong enough/Don't give up/There's nothing wrong with just being yourself/That's more than enough."

Tween translation: You're good enough, you're smart enough, and, doggone it, people like you!

Message for grown-ups: If you tell your child that she's awesome no matter what, she won't hear you. But if Hannah Montana sings it, all will be well.
