Thats a hard question. I would probably pick Dreamboat Annie. That was released in the 70s, but if I had to pick a favourite album from today it would be fanatic, Hearts new album.
Selfish machines~Pierce the Veil The Story of Kristy Killings~Snow White's Poison Bite The Black Parade~My Chemical Romance Feel~Sleeping with Sirens The Drug in me is You~Falling In Reverse Paramore~Paramore k xD
Wow, this is a hard question... I love quite a few albums made by different bands actually... I can't say which album(s) I like best, and believe me, I will not list 173 albums... *EDIT* They are not all modern music, some bands are more in the 80's or 70's.
