Content songs are effective tools especially in an immersion setting. It's a very easy and quick way to learn new vocabulary words that are otherwise boring. Because all learners learn differently, by introducing content materials in art and music form can sometimes peak interest. There will be many more made-up songs by me throughout the year. :)
Tips: Read while pointing with a pointer helps with word recognition. Each word is a syllable, so essentially it's pretty accurate as long as you are not skipping words.
