Our music collections are often not titled properly, and the files have random names. You can have MP3s renamed using the ID3 tag data in the files or vice versa. To do this, first select the files you want to rename. Right click on the selected files and click Library Tools > Fill Properties from Filename to have the tags filled with information from the filenames, or click Rename Files from Properties to use the ID3 tag information to rename the files. From the drop-down menus, you can choose one of the fixed presets that suits the way your files have been named. The same can be done while converting title details to filenames.
