Countless times if you prefer, but the idea is the same anyway  this song has been covered over and over by multiples artists from all around the world. As you suggested, adding one ""notable"" example of each non-English language version of the song would be enough to show how famous/influential is the song. 
In a bit of hurry ? Not really. I simply wanted to clean this section up to reduce its length, nothing else. So I chose removing artists without a Wikipedia article. On the other hand, I don't think adding extra  tags would be appropriate as there's already a ""Refimprove"" tag at the top of the section since July 2013. The best thing to do is to add sources (as reliable as possible). If you can do so then go ahead. I can help you as far as I can but I'm not sure it would be possible to find a source for each artist.   "
