mp3 is not loopable, try using ogg instead.

mp3 is loopable.
Just feed your decoder the same mp3 over and over.
What is not possible is to loop the output of the decoder, because
the decoder might create a lead in and lead out = gaps.

When you loop a mp3 file the only caveat is the padding
at a sample frequency of 44.1kHz or 22.05kHz
The paddig bit is needed at this frequency to
achieve a constant bitrate, and this means that your
input mp3, to be compliant with the standard should be a multiple of 49 frames.
If it is not, I am sure most decoders just dont care.
