How can I fetch a particular data from nested array from JSON file in Angular by using params?

This is my JSON file.

{mood: 
[ {

"id":"1",
"text": "Annoyed",
"cols": 1, 
"rows": 2, 
"color": "lightgreen",
"route":"/angry",

"musics": [
  {
      "id": "0",
      "name": "English- Heaven's Peace",
      "image": "images/music.png",
      "link": "https://www.youtube.com/playlist?list=PLPfXrbtn3EgleopO8DiEdsNKgqYZZSEKF",
      "descpription": "Tunes that soothe your pained soul",
      "reviews": [
          {                   
               "name": "abc",
               "rating": 4,
               "review": "energetic",
               "date": ""
          }
      ]
  },
  {
       "id": "1",
       "name": "English- Hell's Fire",
       "image": "images/music.png",
       "link": "https://www.youtube.com/playlist?list=PLPfXrbtn3EgmZitRQf1X1iYwWW_nUF44L",
       "descpription": "Beats that match the ones of your heart",
       "reviews": [
           {                   
                "name": "abc",
                "rating": 3.5,
                "review": "energetic",
                "date": ""
           }
       ]
  },
  {
       "id": "2",
       "name": "Hindi",
       "image": "images/music.png",
       "link": "",
       "descpription": "",
       "reviews": [
           {                   
                "name": "abc",
                "rating": 4,
                "review": "energetic",
                "date": ""
           }            
       ]     
  },
  {
       "id": "3",
       "name": "Punjabi",
       "image": "images/music.png",
       "link": "https://www.youtube.com/playlist?list=PLPfXrbtn3Egnntch2thUO55YqPQgo4Qh7",
       "descpription": "",
       "reviews": [
           {                   
                "name": "abc",
                "rating": 4,
                "review": "energetic",
                "date": ""
           }            
       ]     
  },
  {
       "id": "4",
       "name": "Mix and Match",
       "image": "images/music.png",
       "link": "https://www.youtube.com/playlist?list=PLPfXrbtn3EglN5LVTETqH3ipRLfXmY6MB",
       "descpription": "",
       "reviews": [
           {                   
                "name": "abc",
                "rating": 5,
                "review": "energetic",
                "date": ""
           }            
       ]     
  }
]
}  ]
}

I have created angular services in a file name mood.services.ts

import { Injectable } from '@angular/core';
import { Mood } from '../shared/mood';
import { Observable, of } from 'rxjs';
import { delay } from 'rxjs/operators';
import { map, catchError } from 'rxjs/operators';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { baseURL } from '../shared/baseurl';
import { ProcessHTTPMsgService } from './process-httpmsg.service';
@Injectable({
providedIn: 'root'
})
export class MoodService {

constructor(private http: HttpClient,
private processHTTPMsgService: ProcessHTTPMsgService) { }

getMoods(): Observable<Mood[]> {
return this.http.get<Mood[]>(baseURL + 'moods')
.pipe(catchError(this.processHTTPMsgService.handleError));
}

getMood(id: number): Observable<Mood> {
return this.http.get<Mood>(baseURL+'moods/'+id)
.pipe(catchError(this.processHTTPMsgService.handleError));
 }

getMoodIds(): Observable<number[] | any> {
return this.getMoods().pipe(map(moods => moods.map(mood => mood.id)))
.pipe(catchError(error => error));
}

getMusicIds(): Observable<number[] | any> {
return this.getMoods().pipe(map(musics => musics.map(music => music.id)))
}
}

And this is my musicdetail.component.ts file which will fetch the data of the particular music that is chosen.

import { Component, OnInit, Inject } from '@angular/core';
import { Mood } from '../shared/mood';
import { Music } from '../shared/music';
import { Review } from '../shared/review';
import { MoodService } from '../services/mood.service';
import { Params, ActivatedRoute } from '@angular/router';
import { Location } from '@angular/common';
import { switchMap } from 'rxjs/operators';

@Component({
selector: 'app-musicdetail',
templateUrl: './musicdetail.component.html',
styleUrls: ['./musicdetail.component.scss']
})
export class MusicdetailComponent implements OnInit {

mood : Mood;
music: Music;
musicIds: string;
errMess: string;
prev : string;
next : string;
review: Review;

constructor(private moodservice: MoodService,
private route: ActivatedRoute,
private location: Location,
@Inject('BaseURL') private BaseURL) { }

ngOnInit(): void {
this.route.params.pipe(switchMap((params: Params) => {return this.moodservice.getMood(params['id']); 
}))
.subscribe(mood => {this.mood = mood;}, errmess => this.errMess = <any>errmess);
}

}

I have passed both mood.id and music.id when clicked in music.component.ts using '[routerLink]="['/musicdetails', mood.id, music.id]"`, on the list of music but I am unable to make logic to fetch particular music to display all its details. I am able to get mood-id using getMood(id) service but unable to do the same for music inside that mood.
