If you hadn't heard of Dr. Luke before Kesha
decided to sue him on Tuesday
, you are not alone – but believe us, you've heard his work.
The songwriter and record producer, 41, has worked in the industry for almost two decades and is responsible for many of the hit songs you sing along to on a daily basis.
Here are just a few reasons you are familiar with Dr. Luke without even knowing it:
He Got His Start on Saturday Night Live
Dr. Luke (born Lukasz Sebastian Gottwald) got a job as the lead guitarist in the NBC show's house band in 1997. During the 10 seasons he performed on the show, Dr. Luke began making a name for himself as a DJ in his native New York City.
Clarkson's "Since U Been Gone," Pink's "Who Knew," Spears's "Hold It Against Me
," Miley Cyrus
's "Party in the U.S.A.
" and Avril Lavigne
" are just a few of the songs that Dr. Luke has had a hand in making chart-topping hits.
He Has Employed Both Kesha and Katy Perry
Dr. Luke owns two publishing companies: Kasz Money Publishing for his own songs and Prescription Songs, which has included artists like Kesha, Perry and Benny Blanco on its roster. Collaborations with these artists have produced hits like Perry's "I Kissed a Girl" and "Hot n Cold" as well as numerous hits for other artists.
He Has No Plans to Slow Down
Though he faces a long legal battle
with Kesha (who is attempting to get out of the long-term contract she signed with Dr. Luke when she was just 18), the producer continues to take on new projects like working with the new girl group G.R.L.
