Use a mapping function to map one property to another object

I have an array of objects as per below.

songs = [
  { 
    track_name: "name of track" , 
    track_genres: ["chamber pop","indie pop"] },
  { 
    track_name: "name of track 2" , 
    track_genres: ["dutch r&b","indie soul", "indie pop"] },
  { 
    track_name: "name of track 3" , 
    track_genres: ["indie pop","chamber pop","indie soul"] }
]

I have another mapping object that looks like this

genres = [
  {
    name: "Pop",
    children: [{name:"chamber pop"},{name:"indie pop"}]
  },
  {
    name: "R&B",
    children: [{name:"dutch r&b"}]
  },
  {
    name: "Soul",
    children: [{name:"indie soul"}]
  }
]

What I want to do is for each track, go through the track genres, and use the “genres” variable to assign the parent genres for each track. Parent genre ideally shouldn’t be repeated.

Expected Output:

const songs = [ 
{ 
  track_name: "name of track", 
  track_genres: ["chamber pop", "indie pop"], 
  parent_genres: ["Pop"] }, 
{ 
  track_name: "name of track 2", 
  track_genres: ["dutch r&b", "indie soul", "indie pop"], 
  parent_genres: ["R&B","Soul","Pop"] }, 
{ 
  track_name: "name of track 3", 
  track_genres: ["indie pop", "chamber pop", "indie soul"], 
  parent_genres: ["Pop", "Soul"] }
];
