You have to add whatever string you want as filename in your multer function.You can add file extension to the file with the following method

const upload = multer({

    storage: multerS3({
    fileFilter,
      s3,
      bucket: 'admin-song',
      acl: 'public-read',
      metadata: function (req, file, cb) {
        cb(null, {fieldName: 'TESTING_META_DATA!'});
      },
      key: function (req, file, cb) {
        cb(null, Date.now().toString() + '.' + fileExtension)
      }
    })
  })
