There are some artists which became successful with an album without getting much attention from their singles, while others became singles artists. Other artists became superstars for both of their singles and albums. However, I am going to discuss here some boybands who became superstars with breakthrough singles which made them superstars.
Backstreet Boys - Quit Playing Games (With My Heart)
The first ever single of Backstreet Boys is "We've Got It Goin' On", which became a top 10 hit in several countries. However, their first sing which made them global stars is "Quit Playing Games (With My Heart). It's the fourth international release of the band from their self-titled debut album, and the second single for their US first album. It was also their first US top 10 hit for peaking at number 2, and third UK top 10 at number 2.

NSYNC - Bye, Bye, Bye
NSYNC achieved success from their first single "I Want You Back" for reaching the top 10 in several countries including UK, and top 20 in the US. However, their album "No Strings Attached" brought them to their peak, and its lead single "Bye Bye Bye" made them superstars. It reached number 1 in some countries, while it peaked at number 4 in the US, and number 3 in UK.
Boyz II Men - End of the Road
Boyz II Men were US superstars already from their first single "Motownphilly" and succeesing singles. But their success became global through the ballad "End of the Road", the theme song of the movie "Boomerang", and was the fifth single of their first album "Cooleyhighharmony". It reached number 1 in the US for 14 weeks, and was their first top 10 and number 1 in the UK. It reached number 1 globally too.
