I've been an In Flames fan since I was 14, I'm 24 now and I still love them. They have a couple albums that I think are mediocre but overall they still kick ass. If you have any doubts about ASOP, try it out...It grew on me a whole lot and I like it a lot more then Soundtrack which is just horrible.
Album Ratings -
Lunar Strain - 7/10...Good Start but something is missing
The Jester Race - 10/10...Classic Metal album
Whoracle - 8/10...Not as good as TJR but still good
Colony - 9/10...My 2nd favorite album
Clayman - 6/10...Stale sounding at times but I still enjoy it
Reroute to Remain - 8/10...Totally refined their sound despite the arguments...Easily my 3rd favorite.
This is where the albums start to go downhill
Soundtrack to your Escape - 3/10...Nu Metal, gay keyboards, no solos WTF!?
Come Clarity - 5/10...Step in the right direction, solos/leads are back every song is pretty decent.
A Sense of Purpose - 5/10...I like this album about as much as Come Clarity, they need to change again for the next one.
