Brazil is HUGELY diverse country music-wise, and we have tons and tons of genres over here... But just a thing... kaled kalil pointed a lot of artists and their main genres, but a lot of the music he posted doesn't really represent the genre those artists are known for, you know? Dançando from Ivete has a lot of zouk to it, while Na Balada from Gustavo Lima is far more eletronic than sertanejo tends to be, and Anitta's Na Batida has a lot of influence of EDM over it. I would put those as just pop music, on the sense that they mix diferent genres in order to appeal to a larger market.
Now, some of my takes:
Axé - High energy afro-brazilian music. Another big names: Asa de Águia, Chiclete com Banana, Luís Caldas, Banda Eva.
Ivete Sangalo - Sorte Grande/Greatest Luck (Our biggest star right now, compared to Ayu, Namie, Madonna, Beyoncé... Ivete as kaled has pointed, is famous because of it, but she actually released on pretty much every mainstream genre we have and has music that goes from guittar riffs directly taken from metal to EDM influenced. This song from hers is more on the Axé side of things and is one of her biggest hits... If she was Ayu, it would be evolution)
Cláudia Leitte - Exttravasa/Overflow (as he said, she is kind of a national joke)
Daniela Mercury - Canto da Cidade/Song from the City(the one who made axé music mainstream back in the 90's)
Brazilian rock Another big names: Paralamas do Sucesso, Raul Seixas, Detonautas, Charlie Brown Jr.
Pitty - Na sua estante/On your shelf (his example was good, I just love this song
)
Cazuza - Brasil/Brazil (known as one of our biggest "poets" from popular music, died young from AIDS, he is a music legend of ours)
Legião Urbana - Será/Maybe (Renato Russo, the vocalist and brain from the band is also a legend and also died of AIDS)
Rita Lee - Amor e Sexo/Love and Sex (our rock grandma, or rock dinosaur as she calls herself, she has been releasing hits consistently since the 60's and ended her final tour 3 years ago being arrested by calling cops pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~s... So, the rock'n'roll is strong on this one)
Sertanejo: Our country music. Traditionally, the biggest acts were duos... Until Luan Santana came. Another big names: Leonardo, Paula Fernantes, Thiago e Matheus.
Luan Santana - Eu não merecia isso/I didn't deserve this (Our pop prince and biggest young star... Lately his singles are mixing with EDM and funk and several other genres... He is from my city, so, I know some people who studied with him
)
Gusttavo Lima - Que mal eu te fiz?/Did I wronged you? (He is market as kinda of a Luan clone, but is big on his own)
Zezé de Camargo & Luciano - É o amor/It's love (Music legends, around and big since the 90's. Zezé is the father of one relatively big act of ours)
Chitãozinho e Xororó - Evidências/Evidences (Music legends, around and big since the 80's. Xororó is the father of one of our biggest pop acts ever)
Funk Carioca: One of our own eletronic music genres... It's starting to get mainstream, but was born on Rio de Janeiro slums. "Funk Carioca" actually means "Funk born in Rio". All the artists I'm picking actually started on the underground funk scene. Other big names: Naldo, Mr Catra, Buchecha, Mc Leozinho
Valesca Popozuda - Beijinho no ombro/Kiss on the shoulder (She was the queen of the underground funk singing openly about sex on a pretty pornographic and tong-in-cheek way... Until this song made she enter the mainstream. The song title is a reference to a charm to repel jealously, kissing yourself on the shoulder)
Anitta - Show da Poderosas/The Divas Show (Probably the person resonsable for funk carioca becoming ultimately mainstream, she is our current pop princess. Her kind of funk is called "charme", a more melodical take on the genre)
Ludmilla - Fala mal de mim/Disses me (She is getting really big lately and is going through a proccess similar to the one Anitta went through.
On a next post I will talk a little about MPB, Samba, Pagode, Bossa Nova, Forró, Brega, Tecno-Brega and Pop. And I think this covers a little of our musical diversity that got on the mainstream.
