Luckily, I recently discovered the addition of my station to iHeartRadio, and that app IS able to run when "minimized" so I no longer have this problem. And to your overall point, I think it will only get better for Windows Phone in the future. You ever noticed how Microsoft makes an awesome crowd-pleasing version of Windows only to follow it up with a dud, but then release another success following the dud?? Think about the history of Windows through the years: '98 but then Millennium, XP but then Vista, 7 but then 8/8.1. See what I mean?? While I don't consider 8/8.1 to be a dud; rather, just a shock to the senses when you first see it which takes some getting used to and it kind of has a steep learning curve (although, the possibilities are nearly limitless--especially in regards to how customizable the Metro UI is--once you master the OS, in my humble opinion), a lot of people don't like it and Windows is listening which means the next version of Windows (Windows 9 or Threshold, depending on who you ask) will be that awesome version in that pattern. The Start Menu is coming back and it looks like it's going to have Live Tile integration alongside the classic look and a lot of issues people have with the current version will be taken care of with Windows 9/Threshold. Couple that with the fact that a lot of people have held off buying new laptops/desktops/devices simply to hang onto their Windows 7 computer and avoid Windows 8/8.1, and there will likely be a FLOOD of customers buying the new version of Windows which may end up making it the most successful Windows yet.
Windows has also struggled because of the lack of quality phones available to consumers. The hardware has only recently caught up to Android phones and only in a few phones (the Lumia 1520, Lumia Icon and the HTC One M8) and they are all relatively large phones which limits the customer base, too. Also, two of the phones are Nokia phones and, even though they are both AMAZING phones, Nokia still has this stigma out there of being stuck in 1999. When I wanted to make the switch, only the Nokia 920 was in my price range and I admit that I was reluctant to get a Windows phone specifically because I preconceived notions about Nokia in my head. And I think a lot of people do.
But the 920 was, AND STILL IS, A GREAT PHONE!! And so is my 1520. But when I told my friends I got a Nokia, they all went, "Really, dude?? A NOKIA?!?! The same brand we all had back in high school as our first phones??" I told them I had the same doubts when I first made the switch to Windows (which I wanted to do because I didn't like that Google, through its Android phones, snooped through all my stuff like my Gmail and my browser history and I couldn’t EVER see myself getting an iPhone because I just hate Apple), but when I showed them my 1520, they told me that their individual opinion of Nokia has been completely flipped on its head which never would've happened without me showing them just what the phone was capable of. And that was before it got the 8.1 update. They all would've just walked on by a Nokia Windows phone and I think a lot of people feel that about Nokia, Windows phones in general, and just about the new Windows UI as a whole.
But it really is getting better. New bargain, mid-range and flagship Windows phones are coming out in the next 5 or so months, and Windows 9/Threshold will be sometime around April of 2015.
And, finally, don't forget that the Windows Store keeps growing every day (and as the UI gains more and more acceptance, so too will it gain acceptance by programmers/developers/3rd party whatevers who will release better and better apps for it that have no problems seamlessly integrating with the OS).
I think Windows has started to pick up some momentum which will, after not too long, become synergistic and will continue to propel Windows upward. I'm excited for the future of Windows and Windows Phones. The possibilities look endless, the sky is the limit and the future very realistically looks bright. Hang in there, Damon and everyone else with concerns: it WILL continue to get better and better.
