[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] eatkabab:
Well I just wiped and installed KitKat yesterday... I actually saw all those failures skimming through it too. Was kinda suprised. I'll see what I can find...

Error occurs on line 7 below

Any help at all? Any suggestions as to getting a clearer picture?

I just uninstalled 8tracks and tried to replicate the problem and it didn't do it. Interesting...in previous installs of your ROM it has been play music or soundcloud too.

And now I just tried using 8tracks mobile website from Chrome and it's WAY faster and smoother than the app itself. The only mobile site that I might actually use... I guess I'll consider this issue resolved until the next flash.
