It's a nice problem to have though isn't it?
I don't carry my music with me nor do I stream. I had my fill of that with cassette tape and Walkman clones.
I can see how some members might have a completist attitude in that they'd have to have all or nothing of the body of work that The Beatles did but where would you stop? With the Fan Club recordings? With the lost recordings of demos recovered? With foreign language versions of their hits?
I've felt I should have their entire works in the past but despite having the means, as we do today, of compiling the whole collection with relative ease, I don't do anything about it. That said, I probably haven't listened to the non-hits so much.
It's not quite the same as with an artist such as Bowie where you hear a song and although you can't relate to it until you've heard it through a couple more times, you know the time you invest in listening will be rewarded. I'd be more interested in having his entire works. This because I feel I can always "get" the essence of a Beatles tune relatively quickly but with Bowie I'd like to have his tunes on hand to really get under the skin of them.
Weeding out Beatles tracks wouldn't be too hard for me. I would start with all of the top ten hits because I have heard them over and over. I will continue to hear them over and over too. That leaves the ones that I may not have given much of my time to in the past. Okay they're not perhaps as deep as Bowie's stuff but they were ten years before and I was still a young child. It's as if Pop Music was maturing alongside of me, becoming deeper and more sophisticated, a bit* like myself.
