Remove text before hyphen in file name?

[Theshawty]

Ok, so I have a massive music collection, over 660 songs and they're all like this: n. Artist - Song

Where n. defines a number from 1 to 600+ plus a dot, like this: 3. Red Hot Chili Peppers - Californication

I somehow messed up the ID3 tags as well so the "title" in ID3 tag is the exact same as the filename, and the "artist" part too. I'd like a way to in the filename remove everything left of the hyphen and the hyphen itself so the filename only consists of the song's name, like this: Californication

I like it well-structured and if I set the filename to only be the title of the song, and I set the ID3 title to the title as well and set artist to, yeah, the artist, it'll look much nicer in music players. Get it?

Sorry for not being able to explain very well what I want. I do not natively speak English.
