MuddleC said, in part:

We all have accents that we hate to hear, but you don't have to listen to the words, just their tune.

Depending what you mean by the above, I may have to strongly disagree with you.

If you mean that the "tune" of the words and the cadences of the words go a long way toward helping with understanding a set of words whose pronunciation or enunciation is difficult, then I'll agree with you. Sort of. It's true that even with speech the "tune" of a sentence and the rhythms with which a sentence may be said conveys (or at least helps convey) much of the message.   But I don't really think that's what you meant.

If you mean (as I think you may)that even if you can't understand the words of a song it's not important because you can just treat the whole thing as music without the meaning of the words, I must object. Strenuously. A song has words for a reason; a song is meant to communicate meaning, which is why it has words. If one just dismisses the meaning that might be intended, then the piece might just as well be only an instrumental. That's why I intensely dislike most operatic singing: either it's in another language, so that the words are lost, or even if it's in English most opera singers have attitudes toward words and habits of pronunciation which are geared almost exclusively toward making a nice noise, at the expense of intelligibility.

If you listen to "just their tune" you're losing much (and I would say most) of the value of the song.
