Why does Carnival Cruises use a song about a heroin addict to advertise themself?

Question

Lust for Life by Iggy Pop. Why not go all out and use Chinese Rocks?

Answer 1

they use that song to make people like you re-advertise their product....

none of us would be talking about carnival cruises right now if they didn't use that song..

Answer 2

You have your cruise lines mixed up...Carnival uses Somewhere (Beyond the Sea) by Bobby Darin.  

RCL (Royal Caribbean uses Lust for Life.  And maybe they use it coz it fits with the advertising theme of people cruising living life to the fullest.
