I agree that it's much more convenient to swipe up to get the 'Now Playing' - I do this all the time.
This is only a beta, though. I expect when WatchOS is finalized, Music will be put into the Control Center just like in iOS 10, so we can keep swiping up like we're used to.
EDIT: I noticed that Apple Music is a complication on the Apple Watch. I didn't notice if it was before? I just added that as one of my complications, and boom - I can now see music, without doing any swiping at all! Plus, I can touch the complication to go in and change the music.
However, it seems to leave music, I can't just swipe, I need to press the crown button. So, not as nice.
