Yeah, I did see that, but the videos I download don't always have their titles in the format that I'd like, or they don't include the artist name or whatever, so I just do it myself.

For example, https://youtu.be/ll0egrmKZj0 doesn't include the song name or artist name anywhere in the title (I prefer this version to the final released version of Stand and Deliver), so I'd have to rename it myself anyway to "Look Mum No Computer - Stand and Deliver.mp3"
