I started listening to Japanese songs. My favorite now is ひこうき雲 hikoki gumo (he-koh-o-kee-gu-moh), which roughly translates to "smoke trails left by airplanes." Hikoki means airplane, and gumo means smoke. The song is actually more than 40 years old but was recently used in the animated movie "The Wind Rises" by the famous director Hiyao Miyazaki. I'm trying to memorize it to sing it in karaoke, which is a very popular activity in Japan. Listening to Japanese songs is a great way to learn and practice the language.
