Thai music: OST. Love of Siam

After hearing so much hype about this new coming of age Thai movie on thai webboard, i started listening to the soundtrack and totally fall in love with these songs. now they made me really want to see the movie. but it definitely should take many more months before i possibly can. it does look like a good movie--plus i heard the story is unusual, at least in the context of thai cinema, and has stirred varied emotional reaction from the audience. To me these songs, while being regular pop songs, sounds strangely hypnotizing, like they are telling a story.
for the trailer, you can find it on youtube:
