iHeart radio help!

maddymama

Hi All,
I am not a techno wizard, but someone who just might need a word of advice. I listen to iHeart Radio when I run. For the first month or two, I had no issues with the app on my phone (HTC Droid). Then recently I've had trouble while running- mainly there is a huge delay between songs. As in the time between the end of one song and the start of the next is between 2 and 5 minutes long, which is an eternity when I'm running. I'm running on the same streets as before, it's the same phone. I'm not anywhere near my data usage limit for my plan for each month. Any ideas on what might be going on?
Here is what I'm wondering, did I switch a setting with out knowing it? Is the app just crazy? Are all the radio/music apps (Pandora, etc.) the same? Should I try another one? Did this happen to anyone else?
Thanks!
