The next band I've got for you is another really well rounded band who is also pretty popular in Asia. FIR originate in Taiwan, and sing all their songs in Chinese. They've got a range of songs, from melancholy to fast and fun, but my personal favorite is a slower song called Wo Men De Ai (Our Love). Enjoy it.
Here is another one that you've GOTTA listen to! The music in this one is amazing, and is truly moving. I feel like I know exactly what's going on, even if I can't understand the words. You can ignore or enjoy the video, whichever you wish.
And here, since I said they were upbeat, is a song that is pretty much a dance rock song. Fun beat to groove to.
They've got multiple albums out, and plenty of other great songs. I suggest you browse around on Youtube, you might find a song you love! Thanks for checking these out, I hope you enjoy them.
