This video starts out mostly in English and shows off some of the dance moves from the popular kpop song 1to10 by Twice Easy Mirrored. You can jump to minute 4:40 and the lesson teaching Korean language from the lyrics in the song actually starts.

Plus there is almost always additional vocabulary and phrases that you can pick up from song lyrics that aren’t common in textbooks. Another alternative is to learn using Korean dramas.
