Meghan Trainor's "All About That Bass" is No. 1 on the Billboard All Female Top 5

The catchy song that is blasting all day on radio stations, "All About That Bass" is now on the Billboard Hot 100! We can thank the 20-year-old singer, Meghan Trainor for giving us such positive dancing vibes. The singer-song writer is followed by megastar and pop-country singer Taylor Swift who holds strong at number two with "Shake it Off." "Anaconda" rapper Nicki Minaj is now at the number three spot.

Props to two bootilicious songs on the Top 100 !

To round out the top five we have Iggy Azalea and Rita Ora's "Black Widow" and Jessie J, Nicki Minaj and Ariana Grande's "Bang Bang."

Congrats ladies! More power to you.

The all-female top five lead has made its mark for four straight weeks. The last time the billboard had top female artists as their top five for this long was 56 years ago.

This streak matches the 1999 all-female billboard with Monica "Angel of Mine", Britney Spears "Baby One More Time", Deborah Cox "Nobody's Supposed to Be Here", Cher "Believe", Brandy "Have you Ever", Whitney Houston "Heart Break Hotel" and Sarah McLachlan "Angel."

Not much is known of the emerging new artist Trainor, but her powerful voice and chart-topping single is gaining her a lot of recognition.

Born and raised in Nantucket, Massachusetts, she was raised by a musical family. When she was 18 she signed on as a songwriter with Big Yellow Dog Music. She has had songwriting cuts with Rascal Flatts, Sabrina Carpenter, R5 and various other musicians.

She wrote "All About That Bass" with Grammy-nominated producer Kevin Kadish. This is when L.A. Reid heard the song and signed her to Epic Records.
