The reviews so far have mostly been inaccurate nonsense. Nuclear Blast have a tonne of bands with melodic vocals, what ARE you people talking about? Are you basing your entire opinion on some compilation they put together? Try Edguy, Gotthard (rock, not metal), Hammerfall, Rage, Avantasia, Blind Guardian, Sirenia, Thunderstone, Hardcore Superstar (rock, not metal), Tarot, Sinner, Threshold, Primal Fear (although they've left the label now), Candlemass, Communic, Mystic Prophecy (now on Massacre Records), Nightwish etc. All on Nuclear Blast, all melodic singers (better than most of the ones on this collection). Metal is a much wider genre than just "cookie monster vocals".
As for this collection I'd give it 4/5 as a free compilation (there's really no need for a second BLS track, they could just as easily put put a track by The Duke, Sebastian Bach, The Black Crowes, Overkill, Ted Nugent or Gary Moore on instead), but 0 if it cost anything as none of the tracks are exclusive and are all lifted from other albums, making it worthless. Free is the correct price for this.
