Not that he would have become depressed: in the Album Luke Bryan sings broadly the usual topics that are accustomed Country fans from Him: American country life and everything connected with it: fun, drink, women and boundless freedom. This time with some (cautious) thoughtful lyrics.
Crash My Party is good mainstream in typical Luke Bryan sound: catchy songs in mostly mid-tempo, sometimes rocky, garnished with steel guitar to Country to produce Feeling. Fans will not be disappointed. I think it is good that he shows little profundity, let's see where this is going in the future!
My favorite songs are the already mentioned Drink A Beer and Dirt Road Diary as well as We Run This Town, Crash My Party un the little getting used to, rocking That's My Night.
