ATC's Planet Pop is a perfect example of a debut album that failed to make good on the promise of a killer single.

The hit in question is "Around the World (La La La La La)," an insanely addictive, hauntingly sexy slice of Euro-dance/Hi-NRG perfection that drove European listeners wild.

If you were grooving in a dance club in Munich, Paris, Vienna, or Milan in the early 2000's, "Around the World (La La La La La)" was definitely among the jams you wanted to hear.

Planet Pop gets off to an excellent start with that gem of a single, but regrettably, most of the other selections simply don't measure up.

There are a few other memorable tracks, including the dreamy (yet very danceable) "Mind Machine," and the Latin-flavored "Notte d'Amore Con Te." The latter has a somewhat Marc Anthony-ish appeal, but with more of a Euro-dance energy -- and while Anthony is known for singing in Spanish and English, "Notte d'Amore Con Te" contains lyrics in English and Italian (one of Spanish's sister languages).

Many of the other tunes, however, are forgettable, and the album's erratic nature can be attributed to the fact that the songwriters vary from one song to the next.

Like so many artists in the Euro-dance field, ATC are totally at the mercy of their songwriters -- in some cases, those songwriters come through for them, but in many cases, they don't.

Planet Pop isn't a terrible album, although it's wildly uneven -- and after the excellence of "Around the World (La La La La La)," one expected a lot more from ATC.
