Regarding stacking, pretty much every clicky, spell or song is haste v1, none of these stacks, only the higher haste % is used despite if the buff "stacks" for stat reasons, the only haste v2 in game are the two ervaj line songs, which had low% haste that stacks but can't break the cap... And there's no haste v3 on p99 at all, so you can be pretty sure that haste never stack there.
