I had downloaded some tracks in FLAC for a friend who wanted them on his PSP. The media manager software didn't support FLACs, so I had to convert them to wave first.

I don't know how often such a thing would come up, as I keep all my music in wave format, and thus never have any trouble like that.

Untagged (or unsupportedly tagged) music just shows the file name. "01. Rise Robots Rise -- All Sewn Up" is good enough for me.
