Various changes were made for Android 4.4, and it seems that the non-standard ShoutCast
ICY
header is not supported by Android.
It seems though that the good people of OkHttp fixed the issue (issue 1 and issue 2) already a few days ago.
What you can do, is simply use OkHttp lib directly in your application and by that you'll use the newer OkHttp version (the one with the fix) and not the one shipped with Android (where you'll have to wait for an OS update).
This will also fix it for your application running on other devices that might suffer from that issue.
