I think that after little depressing "These Days" it was time for Jon to reset his faith, to clear what he want to do and find again who he is and who do he want to be. For me it's time when he tried to find inspirations and motivation for rest of his life. It was the same thing like he did in 1991. He recharged his battery again. At this time he made songs by using all his fears and hopes and even little angry which he hide inside at that time.
And he made it with in very poetic way so it's the reason why we have so great album with fantastic atmosphere.
It's very good time for fans but people usualy don't like that little depressing periods on their lives.In life we have ups and downs. TDays/DA representing "downs" in BJovi and "Crush" is defenitely representing "ups" in Jons life.
