Given the number of available words, it's not quite the same. Musical composition is much narrower, because of the way the musical scale works. You can change medium, but the same notes work together. Word writing has far greater latitude, and what "works" has far more space for interpretation. Which is why songs with lyrics that seem stupid can be hugely popular, much less the case in best selling writers. If writers used lyrical style they wouldn't be taken seriously, unless they were doing comedy.
Music has a different vocabulary, that's all. But equating notes to words and comparing their numbers is wrong on several different levels.
If that argument held any water, software would be the simplest and most repetitive medium on earth, consisting as it does of only 0s and 1s.
