I do love it, and tried to convert my girlfriend, but even I found it a real p*sser having to get up every fifteen minutes (six if you're listening to Ringo's greatest hits.) to flip the things over.
Plays havoc with the concentration (which is important for a gentleman) if you're trying to have a "romantic" evening.
I assume your concern here is having too short a period of time to set set the mood, rather than to accomplish anything, uhm, tangible.
Clearly, there are two options here.
One is to take the 15 minute interval as a goal, a challenge of sorts. "I've got 15 minutes to set the mood, or it ain't going to happen". Might be a bit difficult for the "Ringo 6", but hey, aim high! (So to speak).
Option #2 is to go totally retro: Buy one of those turntables that can stack 4 or 5 vinyl discs (called records in the old days), so that when one is finished, the next one drops down and starts to play. This yields 1 hr or more of continuous music. If the mood can't be set in that period of time, there are likely other significant factors involved.
Option #2a - Some of those retro turntables had a "replay" switch - it'd play one side, then play it again, and again. I suppose one could time certain domestic activities so that they occur in syncrhony with the music each time ...
