Ok so I've had time now to give all three of these a proper listen, and... I'm sorry but they did nothing for me. I'm not saying it was bad by any means, but it just didn't connect with me. The guy has a good voice, there's no denying that, but in general vocals are probably the last thing that grabs my attention when I listen to music, I'm a guitar and drums man personally.
Another thing I found interesting was looking at some of the YouTube comments on these songs, at how "dark/haunting/chilling/depressing" they were. Maybe I've been listening to too much Cult of Luna, but these songs sounded almost upbeat to me
