[android help] Regex to remove track number from song name?

Regex to remove track number from song name?

I have a ListView that display song names and artists. Sometimes, the song names contain the track number and a separator with some in this format

13 - J. Cole - Best Friend 

and others like this

13 - Beautiful People

After some digging around I found that the best way to go about this is to define a regex pattern that will remove any unnecessary characters in the string. Cool. I've looked at other SO questions on a similar topic here and a couple blog posts but still no luck.

This my first time dealing with regular expressions and I find it quite useful, just trying to wrap my head around coming up with efficient/useful patterns.

Here's what I need to remove from the string if it is a match

The track number
The "-" or whatever separator character that follows it
The artist name and the "-" that follows that(Each artist name is listed below the   song, so it would be redundant)

Any help on this would be greatly appreciated as usual guys, thanks!

Edit: The same output that I would like is something like this, with just the song names. No track numbers, and if applicable; no artist names following the "-"

Beautiful People
Angel of Mine
Human Nature
