I thought so too until I actually made a playlist of their hits. I’ve struggled through it once.No interest in their regular albums but I'd go for a Little Mix GH.
my Calvin playlist is one of my most used and abusedCheryl’s Greatest Hits EP would be reasonably good value.

19. Radar (Bonus track)
SHORT, concise and SWEET plus all the HITZ minus a couple of ultry ge(r)ms
+ "Circus" and "Sometimes" and chuck "Lucky" and we are talking
Also radio #1 "I Wanna Go" can take the place of "Radar" thx
US #3 thank you very much. Just missed out on UK top ten but hung around for awhile to rack up some salessorry SWEATY but Radar needs to be a bonus track in every single Britney release until her batteries run out
I don't think even Brit remembers how Circus goes (was it a hit though? I cannot recall) and Lucky IS THERE!
