I think it's because of the talent behind the songs, and the lyrics. Some 영화 use iconic 음악 like Tchaikovsky's. He made some of the most 인기 themes in all of classical music. They also have award-winning composers like Arnie Roth. Other times, they use teams of writers who have worked together before and can come together and make great songs (The Rock 'n Royals soundtrack).
There are also beats that make 당신 want to sing and dance. 당신 could listen to the 바비 인형 as Rapunzel 음악 to relax, and the Princess & the Popstar 음악 if 당신 want to party! If 당신 want something funny, listen to The 쥐 Song from 바비 인형 as the Island Princess. 음악 for Christmas? Listen to the Perfect 크리스마스 and 크리스마스 Carol soundtracks. Then there's the lyrics. There are inspiring songs like "I'm On My Way", "Only A Breath Away" and "Making My Way". There's probably a 바비 인형 song to suit every mood, and I think that's why they're melodious and touching.
