Audio Tag Tool
I rip the Subtext and SoundCore shows from BassDrive stream on Sunday and Monday afternoons, but their id3v2 only have the show the names and descriptions, but never the date. I rename the files with the date, but I still can't see those file names in rhythmbox.
Fortunately, I found Audio Tag Tool and its mass tagging feature based on patterns from the filename. I sent it running through retagging my ripped streams to include the dates from their filenames. That's much nicer now. I may have to run more of my files through there to get proper genres on them.
