It annoys me when bands re-record songs for an album and they end up worse than the originals. I don't mind if they're put as B-sides on a single or on a separate release and I like the rare times when a re-recording is better than the original.
The first example that comes to mind is DIAURA's Incomplete best of. Yo-ka grew heaps as a vocalist and I like all the remakes on it better than the originals.
MUCC's 2017 remake albums are good too, Gallo's Lucifero, Lar~Mia's S/T, and The God and Death Star's After the Addle Apple come to mind as well
