Over the years I have watched many many Thai videos / songs on youtube and can normally predict what is going to happen, much to my wife's annoyance.
Boy meets girl, falls in love with girl, she already has boyfriend, ends in tears
Girl meets boy, boy gets angry and upsets her, superhero handsome boy comes along, all ends happy
If you haven't already you could try "Thai Grammy" in youtube, maybe add "collection" or "karaoke" or something on the end.
You may be looking for the proverbial needle in a haystack but hopefully someone can help you more than I have
