}

// GET Track Object
const track = await api.getTrackInfo(song_id);

// Parse download URL for 128kbps
const trackData = await api.getTrackDownloadUrl(track, 1);

// Download track
const {data} = await axios.get(trackdata.trackUrl, {responseType: 'arraybuffer'});

// Decrypt track if needed
const outFile = trackData.isEncrypted ? api.decryptDownload(data, track.SNG_ID) : data;

// Add id3 metadata
const trackWithMetadata = await api.addTrackTags(outFile, track, 500);
