Rank the Best OS Collabs

[Lopyt]

I don't know how many songs I've heard on here that were collabs, but the 4 way collab with me and Newlstoon and Viku I think is pretty cool, and that other one Viku did with Etherbot.

Also, TriGAK

XStep has some collabs also, which are gauranteed too be good, as they were co wrote by XStep
