The streaming model really makes remembering details difficult.

I used to play only local files, and then during a time at university played in the office music on Youtube. One specific album got stuck in my head, but for a long while afterwards didn't find it again. No name, no lyrics - not a good starting point. I just remembered a pink unicorn and that is was psychedelic rock and that the singer sang with a specific deep voice. After several rounds of research (the same youtube channel is still up) and looking through uploads of the timeframe and their recommendations it turned out I misremembered: The cover had a rainbow cat looking into the distance (https://www.youtube.com/watch?v=1Ea1mYXUcBY, Whoopie cat).

How I remembered was funny. I talked to someone about this, researched while, then talked again, when something came over me to look to the side into the distance with a slightly open mouth - just to suddenly realize that this face was on the cover, not the unicorn!

But actually, I still have that image of the unicorn cover in my mind (one color silhouette, hoofs into the air, but who knows at this point). The Whoopie cat album is definitely one I heard back than and it was the music I was searching for, but the unicorn cover probably also existed in that space and was a different album. Or did I just imagine something based on space stallions (https://www.youtube.com/watch?v=5Otaq2tmNMM)?

After that experience I set up a local music player again and downloaded some of the albums I wanted to remember.
