The_7th_one
Ancient Mariner
Days of Future Past
Not this one either, sorry.Days of Future Past

Uh, Tribuzy - Forgotten Time?
Double no, sorry.Beneath the Remains

Streets Of Tomorrow
Still not the right songs, but you're very near from the answer.Angra - Carry On

No, but you're still on the right path.Angra - Rebirth

Neither, but on the right path either...Nova Era

Game Rules:
If someone can find the right artist before clue 3 is given, the next clue is always the year of release and is only worth 1 point even if no clues are given yet. There are no extra points for finding the artist.
Angra - Time
Still the wrong songs.Angra - Travelers Of Time
But still on the right path... But, think "nova era"... 
So, this rule is useless this time...
