Can't Rename Individual Songs in WMP

Hi. I have a CD of songs with generic names such as 0101Track1 (probably my
dad used some weird CD authoring program) and, it's a custom CD of songs from
different albums/artists. I want to go into WMP and rename them to their
correct names, but if I only change one it will change the rest to match the
album. How can I change them all to their correct names and albums?
