# --description--
With everything set in place, call the `pauseSong()`, `setPlayerDisplay()`, `highlightCurrentSong()`, and `setPlayButtonAccessibleText()` functions to correctly update the player.
Congratulations on completing your music player! Now that we've finished testing and using the shorter songs, we've replaced them with the original tracks specially selected by Quincy for you to enjoy.
# --hints--
You should call the `pauseSong` function.
```js
const splitter = code.split('audio.addEventListener("ended", () => {')
assert.match(splitter[1], /pauseSong\(\s*\)\s*;?/)
```
You should call the `setPlayerDisplay` function.
```js
const splitter = code.split('audio.addEventListener("ended", () => {')
assert.match(splitter[1], /setPlayerDisplay\(\s*\)\s*;?/)
```
You should call the `highlightCurrentSong` function.
```js
const splitter = code.split('audio.addEventListener("ended", () => {')
assert.match(splitter[1], /highlightCurrentSong\(\s*\)\s*;?/)
```
You should call the `setPlayButtonAccessibleText` function.
```js
const splitter = code.split('audio.addEventListener("ended", () => {')
assert.match(splitter[1], /highlightCurrentSong\(\s*\)\s*;?\s*setPlayButtonAccessibleText\(\s*\)\s*;?/)
```
