The following cumulative patch comprises the following chunks:

madplay-input-file.diff
    Read a list of MP3s via "-f file".

madplay-output-dev.diff
    Allow interactive control when playing to an alternate audio device.

madplay-quiet-player.diff
    Get rid of some annoying messages.

madplay-saved-tags.diff
    Save ID3 tags in memory while playing, so that pressing 'i' will
    tell you about the current track (as opposed to displaying the
    information at track start, then throwing it away).
