These 2 songs have lore lol. Melanie is basically getting distracted at work which is the bakery. She’s using her escapism since she’s so stressed out. She’s also hearing what other people have said to her about this other worldly place she wants to be involved in. “They said”. So she loses focus on work and starts deeply daydreaming because the job she has is really stressing her out. Her escapism intensified after the boss gets angry at her and the team. She’s literally in lala land which is why she sings lalala at the end and the song also intensified as both vocal lyrics comes together at the end.
I like how FM mashups combines the two instrumentals instead of having one half one song's lyrics and the other song's instrumental and then after the chorus it switches.
