Yeah, I'm really not sure why Apple is so interested in doing streaming music except that it really is true that music in their DNA.
Streaming music burns a lot of data. Burning lots of data in 4G and LTE devices makes more money for key iPhone-subsidizing partners. Subsidies are key to iPhone sales. iPhone sales are most of Apple's revenue & profit. Rinse, repeat.
Look at each big iDevice innovation the last few years: Siri, Retina, Maps, Facetime, iCloud, etc. What do they all have in common? They all beg for data burn. What's next? The much touted Apple cable replacement video streaming service. Nothing will burn data faster than streaming HD video.
If I'm AT&T, Verizon, etc, I absolutely love the idea of Apple Music. And I'm even more excited about Apple "new model" (cable replacement) solution for streaming video. I'd also like to see Apple keep selling iDevices with relatively little storage because I know the masses will buy the cheapest one and then need to stream more data to make the most of them.
Otherwise, I don't see it either. There's all this spin about how consumer preference has shifted to renting music instead of owning it but that seems entirely based upon new music sales falling off a bit while existing streaming services seem to be adding more users. That LOOKS like the consumers are showing their preference. But I think it's a misinterpretation, ignoring the reality that used CDs are the same as new CDs when imported into iTunes... but they don't count as a new music sale because they've already been counted. Similarly, the drive to re-buy the same music is almost extinct because the old music library doesn't degrade in digital form, so the historical repurchases of on-the-shelf have thinned out. Third, when Junior leaves the nest, instead of having to go out and rebuy his parents music for anything he'd like to have in his collection, he can instead just take their whole collection with him.
Lastly, the biggest issue IMO is the lack of new, quality "must have" music that isn't already in our music collections (in other words, this is a modern music quality issue). Where is the modern day music that is as great as the favorites already in our collection? When I was younger, I'd tune into the "Top 40" programs to hear the best songs in the land. Inevitably there would be 8 or 15 new songs debuting in any given top 40 and I'd probably like 4-6 of them enough to want to run out and buy them. Now, I tune into top 40 programs and I hardly ever hear a song that is "must have". That's not me saying there's NO good music, just not as much (to my own tastes) as when I was younger. That's very subjective- just my own opinion- but, back then, my friends & family did the same generating enough revenues that there could be these things called record stores renting space in expensive malls and paying staff to work there. Now (and again this is very subjective), the music sounds over-produced, overly formulaic, almost the same song (or the same drum beat) over and over again. While there are certainly exceptions, they- IMO- seem relatively few and far between. Maybe this streaming music access to everything and it's "new music discovery" is going to make it possible for people like me to easily find all of this great music NOT already in my collection. I'm somewhat skeptical... but hopeful.
Does that mean nobody wants streaming? No there are always people who want to or have to rent instead of buy (in all things). But is streaming "the future"? We'll see. I think it will look like a massive success in free trial mode. Then, we'll see how many of us want to actually pay for "the future"... especially when- if we like it- we can switch back to Spotify's free tier to continue our free trial experience indefinitely.
