To be honest, I would certainly hope that people wouldn't actually get annoyed because of peoples' differences of opinion. I admit, I winced a bit when I saw the Megadeth and Power Quest songs getting a mere 5 and 6, but differences of opinion is a part of life, whether anyone likes it or not!
I dunno, maybe it's because I'm used to friendly banter about Music taste with someone who pretty much only likes Deathcore, lol.
To go back and give me opinion on some of the other songs whilst I'm bored:
1928, those two songs you posted are great! Never heard anything from either band before so was cool! Also, for Annihilator, I wouldn't say any of their stuff is "brutal" although it is getting heavier with every release it seems (Their older stuff is more melodic). They are an extremely underrated band of the Speed/Thrash Metal genre. Jeff Waters is one of the best guitarists ever and they are one of the best bands I've ever seen live.
I recommend checking out Crystal Ann/Alison Hell, Phantasmagoria, King of the Kill, 21 and The Trend, to name but a few of their best songs. The Trend has probably my favourite intro to a song ever!
Hearts on Fire is a great song of course. Not a fan of Slipknot and that partcular song. I can enjoy Duality quite a bit when in the mood but that's about it.
Skin 'o My Teeth and Temple of Fire are two my favourite songs by their respective bands! It's interesting and surprising that these would get mediocre scores!
To rate the last two songs, I'd give the Chris Daughtry one 5/10. He's got a good voice but the music in general is not my cup of tea.
10/10 for Temple of Fire everytime. As I say, one of my favourite songs by Power Quest and really hope to hear it live one day!
Ok, me next song
Morbid Angel - Maze of Torment
