Does this sound like BIG BANG?

I don't know, but it's horrible.

This sounds like skz's song but have some big bang's touch in it. It's a banger tho

No. Except the clapping beats at the start reminds of bang bang.

I think it's just parts of the percussion + the "party" ending chorus that might remind you of Bigbang.

Otherwise it sounds like…not exactly something SKZ would release themselves, but it reminds me a bit of the songs 3RACHA have written for Yaochen and Show Lo.

Hmmm, I personally don't see/hear it especially if for BIGBANG Japan releases. For Korean releases, very slight.
