Five years after the purchase it clearly looked a winner. It had vaulted them into 2nd place in music streaming and Apple had sold a ton of beats headphones (and still sells tons). If they show signs of decline now that's on the decisions Apple has made in the seven years they've owned both.
And Songza was shut down by Google (like all new Google products) after a couple years and merged into Google Play Music which was shut down by Google (like all new Google products) a few years later to merge into Youtube Music.
If Apple had owned Youtube, I doubt they would have ever bought Beats. They would have clearly worked to build it's music streaming service internally like they pretty much do with every product. Youtube Music is succeeding because of decisions the Youtube team made, not because of some tiny acquisition eight years ago.
BTW: If you think this was a poor end result for the Beats merger, then you are totally unaware of the typical poor results of corporate mergers. Now I have to change my previous position. It didn't just work out okay, it was a spectacular success.
