"A Teens" refers to a Swedish pop music group consisting of four members that gained popularity in the early 2000s. The group was formed in 1998 and was specifically known for covering and reimagining songs by the popular Swedish band ABBA. The members of A Teens were Marie Serneholt, Amit Sebastian Paul, Dhani Lennevald, and Sara Lumholdt.

A Teens achieved wide recognition through their debut album "The ABBA Generation" released in 1999, which included covers of some of ABBA's hit songs such as "Mamma Mia," "Dancing Queen," and "Gimme! Gimme! Gimme! (A Man After Midnight)." Their youthful and vibrant energy attracted a large fan base, particularly amongst teenagers, and their music often appealed to fans of both ABBA's original songs and the newer pop sound.

While A Teens primarily focused on covering ABBA songs, they also released original tracks that showcased their own musical style and talents. They released three more albums, "Teen Spirit" in 2001, "Pop 'Til You Drop!" in 2002, and "New Arrival" in 2003, before officially disbanding in 2004.

The legacy of A Teens lies in their revival of ABBA's music, introducing it to a younger generation and contributing to the continued popularity of the iconic Swedish band's songs. A Teens left a mark in pop music history as a successful cover group, showcasing their ability to reinterpret and bring a contemporary touch to classic tunes.
