Martin Garrix, Confused about scales?? Please help

[Victor Valen]

Ok. In a remake of Martin garrix's song on youtube you can see his chord progression


[h=1](FL Studio Remake: Bassjackers - Crackin (Martin Garrix Edit) Melody + Drop [FLP!]) by Lennard Schroot...[/h]

, skip to 0:50), however I can't find the note scale he is in?? Do you always need to stay in scale to make a catchy melody or chord progression? Thanks.

The key is in G minor, you can check it here https://pro.beatport.com/release/crackin-martin-garrix-edit/1226461

The majority of big room house songs are written in minor
