Unfortunate news about spoilers. Recently, the War of the Damned OST has been released on Amazon, which contains tracks with heavy, obvious spoilers about characters endings. If you do not wish for these spoilers, then avoid the soundtrack at all costs. Again, avoid the soundtrack at all costs if you do not wish to spoil major events.
Steven DeKnight is particularly furious about the situation, but Liam McIntyre and Barry Duffield have noted that in case somebody has spoiled certain events to you, that the final episodes still have twists and turns at will surprise you, and that the titles may not seem what they seem. Still, it is an unfortunate event, and a majorly disastrous turn of events.
Be careful out there.
