These leaks are intentional

The lovely Spacelab people get just slightly over-excited as These Arms Are Snakes put a track online:

These Arms Are Snakes have leaked the song Red Line Season, from their new album Tail Swallower & Dove. Their label Suicide Squeeze says the the song "eerily pummels and shakes punk-rock to its foundation."

So, the band know about it. The label know about. They're promoting it. In what way, exactly, is that a "leak" rather than a "release"?
