Hot take:
Kiss me Once was great, as great as Golden and Disco, it was just released at a time where vinyl hadn't really took off, Kylie wasn't hungry and buying multiple formats of the same release only became a thing the past few years. If it had the same treatment as a release it would have sold 70,000 first week and be considered a classic / great album.
I like Kiss Me Once, but it spent a total of 5 weeks in the top 40, which is probably a better judge of popularity, it had no staying power. Multiple formats really only impact the first weeks sales, so it may have opened with higher numbers but it would have still dropped down quickly. Disco has already spent 5 weeks in the top 20.
