こんばんは！
Here is a fun song that has so far taught me how to say one sentence: エビはかにじゃない。 Maybe this will come in handy someday when... I'm differentiating between seafood? I don't know when it will be useful sentence, but it's still a great song!
Kitasono Minami has quite a few other songs on SoundCloud that I like, so you can go check him out.
Another tip: I learned about this song from http://www.tofugu.com/ , which is a really great blog about learning Japanese language and Japanese culture.
