They have similar production style, Drake and 40 started that anyway.
What do you think that people who buy a Drake album ain't gonna buy a Weeknd one? Thats stupid. 'Take Care' next month will put on a lot of people on to the Weeknd that didn't know him.
He did a remix of Florence Of The Machines new song. I don't think either version is as good as anything on her first album, I hope its not a sophomore slump for her.
