Singing sensation Charice released her sophomore international album “Infinity” in Japan Oct. 5 under labels 143 Records and Reprise Records, though it has yet to be circulated in the U.S.

The 19-year-old Filipino singer has had a busy year as she, in addition to producing the 11-track album, has been filming for her 2012 movie “Here Comes the Boom,” making guest appearances as Sunshine Corazon on the TV show “Glee,” serving as a spokesperson for Acuvue and performing in the David Foster & Friends Asia Tour 2011.

Already, “Infinity” is number 8 on Billboard Japan Top Albums and is considered a remarkable step up from her self-titled debut album in terms of sound, lyrics and energy.

While her first album was primarily ballad-oriented, these tracks have more of a pop, R&B, and dance vibe to them, such as her singles “Louder” and “One Day.”

Her decision for a change in genre was a move on her part to interest more audiences in the United States.

“Japanese, Philippine and Asian fans tend to like ballads and mid-tempo songs while in America, if it’s not an R&B, pop or dance song, it won’t chart,” explained Charice in an interview included in the CD booklet.  “With that in mind, I’d like to continue singing songs that will inspire all types of fans.”

Included on the album are a few ballad songs as well, including “New World,” which will be featured on the international version of the video game “Final Fantasy VIII-2,” and “Far As the Sky,” the theme song for the Japanese television series “Bull Doctor.”

With such a wide variety of songs, it’s actually the ballads which seem out of place on an R&B-, pop-, and dance-dominated album. They seem to drag out with their slow tempo and corny instrumentals.

It’s unknown whether these ballads will be part of the North American version of the album, as they were on the Japanese-imported version of “Infinity.”

Several of Charice’s songs are very self-motivating about being who you are and being the best you can be.

Songs such as “Bounce Back” and “Lighthouse” are very inspiring songs as they motivate others to keep going forward despite bullying, a major issue found today and even in Charice’s own experiences earlier this year, lyrically-speaking.

With self-motivation as the main theme of the album, it was a little weird to suddenly hear songs about failed relationships such as “Heartbreak Survivor,” “Lost the Best Thing” and the Bruno Mars-penned single, “Before It Explodes.”  While they are nonetheless very well done, they seemed to bring kind of a negative vibe to an album about positivity.

Regardless of the mainstream spin on the songs, Charice’s vocals still soar through with the same energy and passion her fans originally fell in love with and with the same ability to hit high and low notes as effortlessly as she did on her first album.

Despite her change of genre to aim towards a young adult audience, the energy of Charice’s maturely-developed voice remains undying.

While an official U.S. release date of “Infinity” has yet to be confirmed, it will be worth the wait for not just Charice’s fans but for all music listeners.  It’s fun, energetic and it sends a positive message about reaching one’s infinite possibilities.

However, for those who are really impatient for the album’s release, the Japanese imported version of her album is now available online for purchase.
