We aren't known for our good pop music, and I think there is a reason ahah but here it's some french singers : fréro delavega, vianney, julien doré, zaz, maximilien, ivick, zazi, jenifer, stromae, and there are so much but I'll just add mika who made some french songs ^^

Sophie-tith, she is very good, and I like her music a lot.
