I never thought I'd fall in love to Thai song (I mean after ATM the Series's soundtrack). Buuuut this song is beautiful. Sing Sam Kan (means The Important Thing) by Endorphine, a Thai band (I guess?). I can listen to it again and again. Specially Lee-za's version (on SoundCloud, please follow this link). Basically, Lee-za's sound is awesomesauce and listening to her SoundCloud stream is one of my daily routine for now haha.. (Hello Liz, just in case you read this, I come from your blog, Pretty-Ugly).
Please listen to it as the meaning is good to (lyrics? Follow this link).
My heart feels warm now... (^-^)
