That's presuming a healthy culture. In an unhealthy culture, some people will feel pressure to uphold some comment that someone "senior" made offhand in a meeting several months ago, even if that leader is no longer attending project meetings. The people who report to this leader may otherwise receive blowback if the "decision" their leader made is not being upheld, whether such a leader recalls their several-month-old decision correctly or not, in the case they recall it at all. I have found it frustratingly-more-common-than-I-would-like where people, including leaders, retroactively adjust their past decisions so that they claim "I-told-you-so" and "you-should-have-done-what-I-said".

In response to your comment, yes, I would largely be in favor of moving forward only with whatever is said in the relevant meetings with the given attendees of a meeting. That assumes a reasonably healthy culture where these meetings are scheduled in good faith reasonable times for all relevant stakeholders.

That is so sad to hear. I absolutely loved Google Play Music – especially features like saving e.g. an online Universal Music release to my "archive" and then for myself being able to actually RENAME TRACKS with e.g. wrong metadata.

That and being able to mix my own uploaded tracks with online music releases into a curated collection almost made it a viable contender to my local iTunes collection.

And then... they just removed it forever. Bastards.

Sounds like we left roughly around the same time and due to similar frustrations.
