I select an album and play it straight in the gym - as in type in the artist, choose the album, double click and play. No playlist needed.

I suppose I could continue to create / delete playlists on the desktop, but it seems like I shouldn't have to. I'll go through the new releases on Friday / Tuesday, queue all the ones I want to try and listen to them one after the other. If I like them, I'll save them to a playlist or add the album to my library. If it doesn't grab me, I won't bother. Regardless, even if I'd queued a playlist, the mobile is still going to overwrite my queue. I just want an option to disassociated the two devices.
