As far as costuming and set go, EXO plays it safe with stylish jackets, oddly lit rooms, and SHINee style haircuts. There are lots of outdoor scenes featuring members who weren't singing so the two music videos, while featuring different voices, were able to be almost the same. It was all very stylish. Thus far, the EXO Planet seems to be a solid "group". Hopefully they'll get ridiculous later on.
Here's their song What Is Love. First in Mandarin, and then in Korean.
Factoid: Mandarin music videos usually have subtitles because Mandarin is tonal and singing changes the tone.
