Apple's acquisitions are few and mostly (IMHO) strategically well thought-out. Let's look at Apple's lala process for clues to where they're going.
Consider the possibility that the lala-buyout/close-down is prelude to Apple's next quantum leap in streaming service. [remember the huge NC data center that's nearing(?) completion]
The "store he doesn't want to shop at" may soon leap-frog what he lacked at lala. I understand that it's probably aggravating at time point to anyone with a substantial investment in lala service, but... the broader implications for overall media streaming/services may surprise us all.
