50 Cent has writing "binges".

The rapper - who is preparing to release new album 'Before I Self Destruct' - says he goes through phases of rapid creativity, followed by disinterest in the songwriting process.

He said: "I write at a rapid pace. I have binges. There's points I'll be in the studio and I've met moments when I'm there and unmotivated by production. Just there and unexcited about the whole s**t. Then there's times when every beat that comes on, I have an idea."

The 'Candy Shop' star also claimed he finds it more difficult to write "commercial hit records" than personal tracks.

He added to MTV News: "When I start writing music to my core, I'm talking about the way I came up, the way I was raised. That's easy to me. Tell me to make a commercial pop record, a commercial hit record and that's more difficult to me than to create concepts that people are excited about where I'm from."
