I don't know the name of the musician nor the band but I do listen to "C'est La Vie" song. It is not famous and it is even in French and Chinese but I do love the melody and the French lyrics. It is about life and how you have to deal with it. It is just so inspiring. I was able to translate the song for 2 years studying both French and Chinese just to decipher its lyrics by heart.
There are many bands i listen to when i'm feeling down but I mostly listen to Paramore, Evanescence. I have always been a huge fan of them and they have so many inspirational songs.
I like the Irish band Cranberries. Even if they are not as active as before, I really like their songs. It speaks of the experiences of people in war, stories to tell of people who have witnessed so much suffering but are still hopeful. I really like them!
