Yes, some of it. Try listening to the song, Skyline, with headphones, while looking at the lyrics to help you notice the holding back. This song is a lot faster paced than the ones I mentioned and will sound very different, but you will notice he’s behind the beat, and is sliding into the lyric, falling into to it really.

You can use Greek yogurt, just know it won’t come out exactly the same.

It’s a bit more tangy than sour cream and doesn’t give quite the same richness, so the flavor and texture will change. The cake will still be good, but different.

If you go that route, use a full-fat Greek yogurt like Fage (it’s less runny) and stop mixing as soon as the flour is incorporated.
