5566

5566 is a Taiwanese boy band that shot to fame in the early 2000s, known for their energetic performances and involvement in television dramas. The group's original five members—Tony Sun, Jason Hsu, Sam Wang, Zax Wang, and Rio Peng—combined talents in singing, acting, and dancing, creating a multi-talented pop group that resonated with fans throughout Asia. Their debut was closely tied to the popular idol drama MVP情人 (My MVP Valentine), which featured their music and catapulted them to stardom.

The band released a string of successful albums, including their self-titled debut "5566 1st album," the follow-up "摯愛專輯" (2nd album), and "好久不見" (3rd album), along with a compilation collection "C'est si bon 最棒冠軍精選." In addition to their music, they contributed to numerous original soundtracks for Taiwanese dramas, helping to define the Mandopop scene of the time. Despite changes in lineup and focus over the years, 5566 remains a nostalgic and iconic name in early 2000s Taiwanese pop culture.
