When I first heard this on the radio, my first thought was "hey, finally 'How Soon Is Now' is a hit!" That opening guitar rift - famously played by Johnny Marr of the Smiths - was used with permission (and 25% royalty - no lawsuit necessary). The Soul II Soul track playing in the background - yes, that's "Back To Life" - isn't as frequently mentioned, but it's also sampled heavily.
No one ever talks about how the Smiths lifted the rift from Bo Diddley, either, but.....
Anyway, this song is poppy and dancy and pure fun. It doesn't matter how many samples they use - this trio (the Cuff sisters who are the vocalists, along with musician Timothy London) makes them all their own.
In my opinion, live, when musicians fill in for the samples, the song really pops.
