At 0:55 in the video for Apple Music, it says "stream from the millions of songs on iTunes, anytime and on-demand." To me this implies any song on iTunes, but I can understand why people would be skeptical of this. My thought is the reason it isn't launching until June 30 is because they're still finalizing deals with other artists/record labels. All Apple has to do is say if you don't let us include your music than go sell your music somewhere else. Correct me if I'm wrong but Spotify doesn't offer the ability to buy music directly, so where are they going to sell music if not in iTunes? Target? I would think every artist would want their music on iTunes. On a side note, I don't know why you think The Beatles and Taylor Swift wouldn't be included. During the keynote, you could at least clearly see Taylor's newest video, Bad Blood, featured in the music video section.
