For want of a Play All button in Apple Music
As has probably most everyone else, I've started my three-month Apple Music trial. I listened to about an hour's worth of Beats 1 Radio on the first day, and found it basically forgettable. (All the "Beats 1 worldwide!" voiceovers during songs certainly didn't help—but I figure they're doing that to prevent people from recording the high quality stream.)
Anyway, I was most interested in the For You feature, as I wanted to discover music similar to what I liked, but that I may not have heard before. Using my iPhone, I went through the "tell us about your tastes" feature in Apple Music, then switched back to my Mac to look at the For You section in iTunes. There I found an assortment of playlists:

Some I wouldn't like, some I would, and (most interesting to me), there were some that had stuff I hadn't heard before. Unfortunately, this is where Apple lost me…
What I wanted to do, as I looked at this wide assortment of music, was just hit the Play button, and let iTunes navigate the entire selection. But I couldn't, because iTunes' playback buttons are all grayed out. Argh!
The only way to listen to these selections is one playlist at a time. But that's not how I listen to music. I enjoy a broad selection of music across many genres, and very rarely do I listen solely to one artist, one album, or even one genre. Why? Because when I do, I wind up getting burned out on that artist, album, or genre, such that I don't want to hear it again for a while.
Instead, I just play music, paying no attention to genre, artist, or album. And once I start iTunes playing, it's typically playing all day without any interaction from me. But if I want to use Apple Music's For Me, I'll have to return to iTunes to pick new selections as each selection finishes. Honestly, for something that's background as I work, that's too much effort.
In the end, as much as I'd like to use the For Me feature in Apple Music, I just can't see myself doing it unless Apple adds a Play All (random, of course) button. Please?

When you have two drives in iTunes, you'll see one CD icon in the iTunes 12 bozo bar—that's my name for the row of device controller buttons seen at right.
