Renaming songs

[billyo]

i had nothing to do Friday so i decided to renamed some of the songs, some of my songs are in caps, and some are not, and i also noticed that some of my songs has the artist name in the song title and vice versa,so i decided to make them all uniformed and corrected the mis titled songs, i did it by right clicking the songs, and typing the right name etc. when i got done on some of them, i closed MS and re-open it a little later , the only ones that changed was the mis-titled song, the rest stayed the same, is there any way to renamed or edit these besides right clicking..
