Apple Music is finally available and with it Apple enters the subscription streaming music game up against power players Spotify and Rdio, something the once-kings of digital music have avoided until now.

The service was announced a few weeks ago at the World Wide Developers Conference, but the details are a little confusing. Don't worry. Here are the seven things you need to know to get going as soon as you update your iPhone.

1. Launch Time

Apple Music launches Tuesday, June 30. Senior director of Apple Music Ian Rogers has tweeted that users should update their iPhones at 11 a.m. in advance to get Apple Music. An hour later, at 12 p.m., Zane Lowe will kick off the Beats 1 radio broadcast from Los Angeles.

2. Price

Apple Music is $9.99/month or $14.99/month for a family plan that can accommodate up to six users. Like Spotify and Rdio, this includes offline listening and unlimited streams from the Apple Music library. There is no free tier for on-demand music.

Apple is offering a free trial, though, for the first three months to try to lure established users over from its competitors. (And, yes, in case you've been living in a cave, artists will get royalties thanks to Taylor Swift's not-so-flexible request.) 

Meanwhile, Apple Radio (including the flagship Beats 1 station) is free to anyone who can sign in with an Apple ID and will include advertisements. An Apple Music membership adds unlimited skipping ability.

3. So . . . iTunes?

iTunes is not dead. I repeat, iTunes is not dead. You'll still see that little purple iTunes Store icon on your iPhone whether you want to or not, and those customers who still prefer to buy their music one $1.29 track at a time won't have to change a thing. Everything you already own on iTunes will be seamlessly integrated into your Apple Music library, so you don't have to rebuild your collection from scratch--even that embarrassing album you bought back in 2007 that you don't want anymore (for now, you're stuck with it).

4. The Catalog

Not everything available on iTunes is available as part of your monthly subscription. It's still available on iTunes, and if you buy it separately you can stream it, download it, and play it wherever. The experience will be seamless and you won't really notice after that initial purchase that it's any different from music you don't own. Google Play already does this, but it's important to note that we won't really know what's in and what's out until the service launches. There will be over 30 million songs at launch, but whether any of those are by The Beatles or Led Zeppelin (two streaming holdouts) remains to be seen.

5. What's Connect?

Um. Good question. The details of the hyped Connect tab in Apple Music are still cloudy, but it's essentially a feed in which artists can share multimedia content, users can comment on the content, and artists can then comment back. You follow the artists you want and any artist, big or small can get verified and have a Connect account which they can post to directly. Ideally, it's a way for artists and fans to interact in a casual, low-stakes way.

At worst, it's a closed off version of Tumblr that's clawed its way into your music player. Acoustic versions of yet-unreleased songs? Yes, please. A bunch of blurry selfies in dark places? Hard Pass.

6. Bells and Whistles

Apple Music has doubled-down on little features in an attempt to separate it from the very-crowded pack. Of the less forgettable ones: There's a bubble-filled interface, reminiscent of the Beats Music app, under the Discover tab that lets you select genres and artists that you like to varying degrees and then Apple Music will make playlist and album recommendations accordingly. You can also ask Siri to "play the hits from 1982" or "play more songs like this."

But even if these work as well as Apple suggests, these aren't going to be what gets you to switch over from Spotify long-term.

7. Human Curation

If there are two words that Apple Music is betting everything on, it's "human curation" -- the idea that their streaming service has better taste than their competitors. You can see it in the Beats 1 radio station to playlists assembled by actual people instead of by algorithms to collaborations with Pitchfork and Rolling Stone.

There's lots of hand-wringing about whether a human can make a better playlist than a program, but that's not the point: there's culture surrounding art compiled by humans that doesn't come into play with algorithmic lists of songs. (It's one reason we've always loved Songza.)

Apple wants you to think of Apple Music as a place to learn about music and to experience music culture, not just to listen to songs on demand. Whether that's what listeners what or not is another story entirely.
