Well it was really hard .
Hint : "
like I am on the floor at my end"  = As I lay Dying , the band , a Metalcore Band I appreciate from US .
Hint :
 Lambesis in 2012 . = Tim Lambesis , the singer of the band, 2012 is the year of the album  "Awakened"
Hint : 
Last time was Decas. = Decas was the previous album.
Hint 2 : 
between wasted words and overcome. = Wasted words is the previous track on the album ( track 4 ) and Overcome the Track after ( Track 6 ) on the "Awakened" Album, so the track of the game is "Whispering Silence" ( Track 5 ) .
"
Each little piece begins to stack up 
Now suffering under the weight of my choices 
And I hardly recognise myself 
Somewhere along the line 
There stopped being lines at all " is the first part of the song. 
following lyrics are : 
Whispering silence The subtle contradiction Compromise creeps in ...That's it  

 Sorry it was really hard , I hope that don't kills the fun of the game. 
But, as Miss Rukya said  

 I posted the 3rd line of the song, so maybe if anybody just had said : "And I hardly recognise myself ", hi hi hi that may become a winner
