I am recently having this problem with my account as well, as of about two weeks ago. I've been keeping an eye on it, and this thread, hoping that it will be resolved, but it hasn't yet. Unlike Kepler, I didn't recently switch to Premium--have had that for a long while. I haven't done anything different with how I listen, and my stations have never been set to Artist Only.  I had recently checked my "hours listened", which I do occasionally to see the order of my most listened stations, so I can give you a fairly accurate account of how it changed. My most listened station: Thomas Newman was at around 1320 hours, is now 2111 hours Next: Maranatha was around 680 hours, is now 6,626 hours Next: Quiet Metal (renamed from Doom Metal) was somewhere in the neighborhood of 550 hours, now 6,109 hours Next: Reading Music (renamed from Electronic for Studying) was approx. maybe 480-520 or so, now 14,707 hours (was saying 16,000 some odd hours, went down to 15,000, now 14,707) As you can see, it is off the charts messed up, and still changing a little here and there. Also, my "recently listened" is changed drastically. Everything going back to Jan. 2019 seems to be correct (at one point that was not the case either, but it changed at least that much a few days later), but everything before Jan. 2019 says "never listened", which is not accurate. I've been a Pandora listener since 2010, and have never seen this happen. It is disturbing. I hope this will be fixed soon.  ... View more
