*) Handle mp1 and mp2 files (including files with mp3 suffixes)
*) add support for playing aac streams (gee, thanks icecast)
*) parsing of lame tags (including getting replaygain and gapless info)
- *) implement apev2 and id3v1 tag reader from xmms-musepack plugin
- *) only use libid3tag for id3v2 tags, use internal impl for id3v1 tags
*) aduio output
*) allowing "pausing" of audio output devices
