[M M]

More data: the delay happens on a real Nexus 5, but not in a Nexus 5 emulator.  No delays in the emulator.

> I'm writing an Android app to play streams. I use the standard Android "MediaPlayer" library to play streams. I've noticed that some streams start playing without much delay (MPR), but others take quite a while to start (WFMU). The only thing changing in my code is the URI of the Icecast mountpoint. My test device is a Nexus 5 running Android 5.1.1.
