Next time you pick up a new album, look a bit closer at the packaging.

The process of going into your favorite record store and picking up that new album by Jennifer Lopez just became a little more complex.

There are now two versions of the pop singer’s album “Rebirth.”

For the normal fan who just wants music, there is the regular album with only the music.

For die-hard fans, though, there is the DualDisc, a new format that has both a CD side and a DVD side on the same disc. The DVD side of “Rebirth” features a documentary and added videos.

The popularity of DualDiscs is slowly on the rise, with acts such as Canadian pop-punk rockers Simple Plan selling nearly a million copies of its sophomore release “Still Not Getting Any” in DualDisc format.

“Record companies are thinking of ways to make the product that you buy in stores more unique than just downloading the songs,” said Mark Cerny, owner of Record Rev, 817 W. Lincoln Highway.

The second side offers fans about 20 minutes of video files and has the entire album in 5.1 Dolby Digital surround sound.

“The added value isn’t worth it,” said Steve Warrenfeltz, owner of Kiss the Sky, 59 S. Randall Road in Batavia. “If it was something along the lines of bonus tracks and live footage from tours, then more people would be interested.”

Originally, when a band wanted to release both an album and DVD, it would package them together as separate discs. Such is the case with Dashboard Confessional’s “MTV Unplugged.” The first disc is the audio aspect of the live recording and the second is the show on DVD. It surpasses the 20-minute mark, however, by the fifth song. Producing this album on DualDisc would be difficult.

Though DualDiscs are new to the market, several audio formats have come and gone.

Several years ago, Super Audio CDs, better known as SACDs, became available. SACDs needed a certain kind of player to experience the surround sound offered.

“SACDs are really confusing to to the consumer, ” Warrenfeltz said. “It’s tough to educate people about them.”

DVD-Audio discs have a sound quality that exceeds normal CDs and DVDs, though special components are needed for the added features.

While the older generation focuses on big-name electronics and the latest gadgets, most college students depend on playlists from computers for their music needs.

Kiss the Sky plays all its music through a computer system and places monitors around the store so customers can see what is being played at all times.

“The last decade or so has taken the focus off big stereo systems and more toward portability,” Cerny said. “I’ve had people sell their entire music collection to me because they have put everything onto an iPod.”

“True music fans continue to buy so they actually have a hard copy of the album,” Warrenfeltz said. “People who don’t buy don’t care about the artist or the music industry. They just don’t care.”

Though DualDiscs are the current rage, some retailers speculate it may take only a few years or months before they go the way of the MiniDisc.

“Who knows?” Cerny said. “They might invent something in the next five years that will put everything out of production.”
