Files lens should search music ID3 data

Often song files are named something like "<track> - <song title>.<filetype>" or "<song title>.<filetype>". For example, one song in my collection is "Tumbling Dice.mp3" (what a good song). Searching purely for filename, you'd have no idea that this was a song by The Rolling Stones from Exile On Main Street. It would be nice to use the Files Lens to search for Rolling Stones and see all of the songs by them in my library - perhaps even with album art. Exposing ID3 values to the File Lens search would be pretty cool.
