Also, MP3tag ,is a tag editor that is really good, it can also rename files from the tag if you choose. Mp3tag - the universal Tag Editor (ID3v2, MP4, OGG, FLAC, ...)
however, if you want to save time then also use winamp,
when you have a ripped cd with the file names track 1, track 2 etc
then opening it in winamp and highlight all the tracks in the now playing field right click them and click send to/auto tag.
This will download all the meta tags for the tracks.
then once done you can open the folder in mp3tag and click the tag to filename.
this then saves you typing all the tracks in the folder.
usually the tag to file will show tracknumber, album ,artist,year etc but you can change the order .i have mine set to track number ,trackname and artist.
it may sound a bit complicated at a glance but when you actually do it its easy after a few times
it has saved me hours of editing folder file names.
