My favorite movie soundtrack

My favorite soundtrack is "starstrukk"(追星族) singing by Katy Perry and 3OH!3(An electropop duo).Although it's a great song, I was pretty confused after the first time I watched the MV of this song, but after I knew it was a soundtrack of movie "When in Rome" everything make sense.The movie is talking about a woman is single for a long time, even her younger sister got married, she's still alone.One day, she went in a foutain of love and picked up some coins, but she didn't know it is said that people will fall in love if you took their coins! And many funny things happended after it.So that's why the MV started in such a strange way.Though there's still many starange part in the MV(such as eating sushi on a rock climbing wall).Besides, this song seems to be Katy Perry's first soundtrack,so it's a big plus for me.
