I would be led to believe that it is because your phone would try to jump on every hotspot that it could despite the data rate being too slow for the app.
It could trigger iOS to report your location near a wifi accesspoint, that causes location to jitter, effecting run tracking accuracy.
Running along a sidewalk, getting good satellite GPS. You pass a house with an accesspoint in Apple's database, your wifi chip sees it, Apple's location stream glitches you over closer to it overwriting GPS data. *shrug*. Grasping at straws.
If you are an Amazon Prime member they have a new service called Prime Music. Free with no ads! Online or stream to your phone with an app.
If you have amazon prime, they just unleashed to prime members their entire library of mp3's. You could look into that.
is spotify basically just Pandora and Itunes radio?
I have an actual radio...That's like a two-dollar goodwill investment, and it's unlimited free music all day/every day.
Sounds like a lousy option. Not only does it cost you at least some money, but there's limited stations to choose from, you're definitely dealing with advertisments, and there are possibly reception issues too. On top of all that, I suspect this Goodwill radio of yours can't really be used while jogging, and probably doesn't have an earbuds jack anyway.
I'd try and get my money back if I were you.
