The main thing that jumps out to me as a possible sampling is the percussion.

The main lower pitched percussive sample in L&R’s verses + choruses also runs throughout all of Cupid Shuffle. They have the same hi-hat rhythms at times (8th notes) and clap sound on beats 2 + 4. https://twitter.com/onefinestgroup/status/1294487477973991424

So if L&R JUST had claps on 2+4 or JUST the hi-hat, that wouldnt be plagerism(unless Cupid created those samples &didnt sell them).

But it’s the fact that all 3 of those sample sounds AND rhythms from Cupid Shuffle are in L&R that Cupid has the right to ask @pledis17_STAFF for $

Diving in a little deeper, the lower pitched percussion sample in Left & Right is not playing the same rhythm as Cupid Shuffle’s.

Shuffle’s loop hits on (1 & 2 & 3) & (4 & 1) & (2 &) 3 & (& 4)

Left & Right’s loop hits on (1 & 2 & 3) & (4) & (1 & 2) & (3 & 4)

So now it’s just time for Pledis and Cupid to communicate with each other.

Maybe the percussion samples they both used were purchased legally (or were free domain) and Left & Right happened to have an very similar groove to Cupid Shuffle in order to create a specific feel/vibe!
