No disrespect, but the music screen only has 5 unlabeled icons - the 3 for player controls are all pretty clear on what they do, which leaves you with the to go back to the playlist and the "dotted burger" (sesame burger? I dunno). I'm sure you're exaggerating the amount of time for effect, but I do have a hard time believing it took too much time to find it if you knew it existed already -- your options were extremely limited.
"[Knowing] it existed" I think is half of the issue with a lot of things, and I'm personally still not sure on the best way to introduce a new UI option to users. Forced tutorials, pop-overs, and so on are very annoying on first use and rarely give out the information that people want to know. But not having anything and no indicators of interaction also makes it really difficult, especially since manuals are so '90s and uncouth for modern software. But I think a lot of times the biggest issue is that you just don't know what your software can actually do.
"Intuitive" is kind of a crappy word to use for a lot of the UI things going on in programming these days, since a lot of the times I'm not sure what to expect when I want to do something. The burger button has become ubiquitous enough to know it's a general settings menu, but for the rest it's hard to really make any sort of analysis on "intuitiveness" since I think a lot of people just aren't sure what to expect. Like, using the music player on iOS as an example, clicking on the song title while on the "Now Playing" screen. This let's you rate the song, and I can't really say if that's intuitive or not, since I can't honestly say what I'd expect from clicking on the song title in the player. All other contemporary programs (iTunes, Media Player Classic, foobar, and others) don't do much of anything except toggle through information on some of them when you click the title, so really, I have no expectation when I touch something on the screen that I will be prompted to rate the song. Embarrassingly, this has left me with a slew of songs with ratings all over the place just because I either pocket rated or did so when I fumbled a touch and just didn't bother to go and correct it.
Touch, for as long as it's been around, is still kind of new territory for getting the most out of the UI/UX stuff, and because the means of interaction is so significantly different depending on the person (i.e., hand/finger size will determine your accuracy), it's far harder on a smaller touch interface to make a ubiquitous experience. With feature creep still being a thing, I think companies need to better audit their software and determine what needs to be introduced and what is fairly reasonable for the user to just play with and learn.
