Yeah both songs are good, I've been trying to find it but to no avail. There's a full but crappy quality version on Broadcast Thai tv site which is why I didn't rip it. Quality isn't worth it but at least you get to hear the full song. The drop down menu at the bottom gets you to the other song.

I think Tanya goes after Nampueng mainly cause Chai really loves her. He's a cheater but I think she's the only one he loves for real. Every lifetime they get reborn to get together. But not only that compared to her life, Nampueng had it easy. Everyone loves and respect her cause she's super sweet and that's the life that Tanya thinks she's entitled to as a Jao. I feel bad for her cause Chai did do her wrong but her going after Nampueng sucks.
