Chances are this is a gimmick of little commercial value, because the advertising will reach relatively few people. However, the fact that they actually built it still saddens me. It's not enough that every empty space has to be filled with advertising, now people can't even rest their heads without hearing it! I mean, people will make the effort to avoid it (by using pillows or leaning on something else) - but they shouldn't have to!

"Passengers got surprised and enjoyed this new form of advertising"
I'm not surprised that they were surprised, but I'd be really curious to know how the company determined that they enjoyed it. My bet is on this statement being a typical marketing lie.
