How to focus on a list item with useRef react hook

I have a dynamically generated array of list items

const  ArtistProfile = props => {
  // api data
  const tracks = props.data.artistTopTracks && props.data.artistTopTracks.tracks
  const [songs, setSongs] = useState(null)
  const songRef = useRef(null)
  // effect hook that creates list of SongListItem components
  useEffect(() => {
    if (tracks) {
      const trackTags = tracks.map((track, index) => {
        if (index > 4) return 
        return (
          <SongListItem ref={songRef} role="button" key={track.id} onClick={() => songRef.current.focus()}>
            <SongTag
              image={track.album.images[1].url}
              duration={msToTime(track.duration_ms)}
              name={track.name}
              explicit={track.explicit}
            />
          </SongListItem>
        )
      })
      setSongs(trackTags)
    }
  }, [tracks])
  return (
    <ArtistProfileContainer>
      <ul>{songs}</ul>
    </ArtistProfileContainer>
  )
}

Im trying to use the onClick event to focus on one item in the list. All my list items are passed this ref const songRef = useRef(null) and I'm using the songRef.current property to focus on the element I'm clicking on. This isn't focusing on anything when clicking so none of my styles are changing.

const SongListItem = styled.li`
  background-color: #1d1d1d;
  :focus {
    svg {
      opacity: 0.7;
    }
    background-color: #181818;
  }
`

I'm trying to achieve the same results you can see on this Spotify link https://open.spotify.com/artist/5K4W6rqBFWDnAN6FQUkS6x

If you hover over the "Popular" songs you see the styles change temporarily, but once you click it keeps the changes until you click another song.

You just can't focus on li: https://stackoverflow.com/a/30213871/7763883

Add

<li tabIndex="-1" ...

And it will work.

There are tabIndex's in your example.
