That tracks had id3 tags, I am sorry for the confusion... again. In russian id3 we have serious encoding problems (deprecated 8bit cp1251 and utf8 mixed).
I don't want to sound like negatron, but I don't think it's very useful for tracks, that we have already on device. Maybe, when recording few seconds of track via microphone (that we hear in radio, or so), but it's still a "gadget" only.
Of course, if someone is really willing to code that, and it won't increase memory footprint for casual use - why not.
