注意 / Note：だらけ often carries bad reviews; まみれ is an object that covers a surface; ずくめ is all one color or one whole type of thing.
比較 / Compare：Same song: 〜まみれ／〜ずくめ. These models are often mistakenly chosen for each other — carefully read the 接続 and nuances above and then decide.
よく出る形 / Common form：名詞＋だらけ。is ONLY used for bad things, and doesn't necessarily stick to surfaces — 間違いだらけ is fine, ×水だらけ is unnatural.
