Awesome. I will consider both options (I am preferring bumping the rank though). Thank you very much.

gst-inspect-1.0 avdec_mp3 will show you that it has a rank of 0, which means playbin and decodebin won't consider it for autoplugging. This is mostly for historical reasons, we should probably retest and reconsider this and give this element a rank.
You need to install either the 'mad' element/plugin from gst-plugins-ugly (note: GPL run-time license), or the mpg123audiodec element from gst-plugins-bad. Or change the gst-libav source code to give avdec_mp3 a rank of GST_RANK_SECONDARY or so.
