OK, so... Both songs are very enjoyable to listen. Be'lakor has many cool riffs on this song. Predominantly they sound like a less epic Insomnium, with some Dark Tranquillity-ish and early Katatonia-ish riffs, but devoid of all the vocal catchiness of those 3 bands. Be'lakor's vocalist is just way too one-dimensional and the unmemorable vocal lines aren't helping him at all. But it's just this song, and I think MrK or someone else said that this is from their worst album. So I'll give them another shot.
Lunar Aurora is slightly more original, with a kickass depressing af atmosphere and mad shrieking vocals. They are also totally uncatchy, even less than Be'lakor. Still, the atmosphere is better, and they will likely lose this one, so I gave them my vote.
