Icecast - Sep 2015 - Delay playing some streams on Android

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.

http://current.stream.publicradio.org/kcmp.mp3?starts playing in about 2
seconds. ?It's a 128 kbps stream from Minnesota Public Radio.

http://stream0.wfmu.org/freeform-128k?starts playing in about 9 seconds.
?It's a 128 kbps stream from WFMU.

The problem gets worse as the bitrate goes down. ?32 kbps streams take quite a
while to start.

I don't notice this problem in iOS code I've written. ?I also don't
notice it in VLC.

You can view the headers with:

curl -s -D - http://current.stream.publicradio.org/kcmp.mp3 -o /dev/null

StackOverflow has several posts about this. ?For
example:?http://stackoverflow.com/questions/6582908/why-does-it-take-so-long-for-androids-mediaplayer-to-prepare-some-live-streams.

Any idea what's going on?

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