Do you actively listen to the music on RR (e.g., pay attention to artists, melodies, instruments, albums, etc.), or is it mostly for some passive reason (frame of mind, mood, focus aid, etc.)? During work, or when I studied in the past, RR music definitely helps my focus. I tend to be an active listener, though, so I must keep it to a low-volume level to not get distracted. When I'm listening to RR for pleasure, then I definitely pay attention to the details. This is obviously true when I'm rating a song. I still remember some minute details to some of my favorite songs, and I immediately recall them when the song comes out of the queue.
