NOTE: I'm not working at the company where I worked when I posted this question, therefore, even though some great answers might come in, I won't actually be testing them since I don't have a reason to (other than promoting the community; which might cause me to do it one day).
If however, some answer to the problem is promoted by many other comunity members, I might opt to select it as the correct answer for the problem experienced so many years after I originally posted the question.
In the meantime, I hope some of the answers may help some of you also experiencing this problem. Yay for Stack Overflow!
Our application has to stream music from an online source (I'm not at liberty to disclose that source).
Why does it take over 2 minutes to start streaming on the S3?
I've been able to figure out that the Media Player object goes into the Error state due to MEDIA_ERROR_UNKOWN - great. Doesn't help me much. So upon handling this in onError with an OnErrorListener, I reset the Media Player object and then call startPlaying which does the rest - setting the data source, etc.

The answer to this question turned out to be an issue on Android firmware installed on Samsung S III devices running Android 4.1.2.
It seemed to have been something relating to the source of the stream, because some sources eventually played on the device, but the one we needed, never played.
If you can get your stream from another source, it should work.
So if you're developing an application for a specific company/purpose and have some control over the source of the stream, or can communicate with people in control of the source of the stream, get them to change the source of the stream to something that'll work on a Samsung S III running Android 4.1.2.
Other than that all that will solve this is a firmware upgrade.

For everyone struggling with this problem here's the solution:
Android MediaPlayer takes long time to prepare and buffer
EDIT : The previous solution is not very complete because it is possible sometimes to hear the player 'stutter' when it pauses and resumes.
A 100% java answer that is slightly more elegant involves using a MediaCodec instance to turn the mp3 into PCM data to feed to an AudioTrack instance.
I have posted full source code and explanation here : http://www.piterwilson.com/blog/2014/03/15/mediacodec-mediaextractor-and-audiotrack-to-the-rescue/

I resolved this issue by using library
compile 'com.devbrackets.android:exomedia:3.0.1'
