# --description--

Before playing the song, you need to make sure it starts from the beginning. This can be achieved by the use of the `currentTime` property of the `audio` object.
Before playing the song, you need to make sure it starts from the beginning. This can be achieved by the use of the `currentTime` property on the `audio` object.

Add an `if` statement to check whether the `userData?.currentSong` is `null` or if `userData?.currentSong.id` is strictly not equal `song.id`. Inside `if` block, set the `currentTime` property of the `audio` object to `0`.
Add an `if` statement to check whether the `userData?.currentSong` is falsy *OR* if `userData?.currentSong.id` is strictly not equal to `song.id`. This condition will check if no current song is playing or if the current song is different from the one that is about to be played.

Inside your `if` block, set the `audio.currentTime` property to `0`.


# --hints--

You should create an `if` statement with the condition `userData?.currentSong === null || userData?.currentSong.id !== song.id`.
You should create an `if` statement checking `userData?.currentSong` is either `null` or `undefined`, or if its `id` is not equal to `song.id`.

```js
assert.match(code, /if\s*\(\s*userData\?\.currentSong\s*===\s*null\s*\|\|\s*userData\?\.currentSong\.id\s*!==\s*song\.id\s*\)\s*\{\s*/)
assert.match(code, /if\s*\(\s*(?:(?:userData\?\.currentSong\s*===\s*(?:null|undefined)|!userData\?\.currentSong)\s*\|\|\s*userData\?\.currentSong\.id\s*!==\s*song\.id|userData\?\.currentSong\.id\s*!==\s*song\.id\s*\|\|\s*(?:userData\?\.currentSong\s*===\s*(?:null|undefined)|!userData\?\.currentSong))\s*\)\s*\{/);
```

You should set `audio.currentTime` to `0` inside your `if` block.
