If you've read any of the "MP3 is dead" articles, you need to know that's absolutely not true.
Here's what actually happened: the patent for the MP3 format has expired, and this is a GOOD THING. Now EVERYONE can use the format without paying royalties to Fraunhoffer - including you, if you're programmer.
In other words, it's actually the opposite: MP3 is supported everywhere and is now completely royalty free and open source.
