I tend to throw new music I discover on Qobuz into the queue for eventual listening. It may be weeks before I finally listen to it. Sometimes I rearrange the queue a bit depending on my mood today, and it could be 2-3 months between putting something on the queue and having it play.
I tend to forget what I’ve queued up.
So, my question is, when I’m looking at a track or a piece of music in the library, is there any clear indication of whether it’s already in the queue?
