Which collaborations have you appreciated from artists that have appeared in BJSC?

This was inspired by currently enjoying this electro bop from Fljótavík's CFCF and my EQ:

CFCF - ultra-obscene! (Piel a Piel) (feat. EQ)

Oh another obvious one that comes to mind for me is a collab that finished in my EOY top 10 for 2025!

akiaura, LONOWN & Baby Jane - Deathwish

Kathaldazia previously sent akiaura & LONOWN while Baby Jane was also entered by Cor Lupus and Lookylion. What a stomper of a drop!

A recent banger for the children 🖤

Pestolia feat. my fourth entrant

And of course this predates my fifth entry & the Cumulonimbia one by another 25 contests:

This is my favorite, and I believe it was actually sent to a spinoff:

Jadakissnia's current artist in an Echoberyl remix! This was #50 in my EOY of 2024.
