Work with Lady Gaga

Jim was interviewed by Rap-Up about his collaboration with Gaga. “I was in the studio with a writer (Kalenna) working on tracks and ideas for random artists and this girl came over,” he revealed. “She looked bugged out like she was out late the night before. It turned out it was Lady Gaga, and this was probably three months before ‘Just Dance’ came out and blew up.

Gaga happened to be writing for another pop singer when the song came to fruition. “I gave her some music and she went to work in a back room. I think she was writing an idea for Britney [Spears] and it was sick, so I grabbed her and brought her back in the room.

We started writing a song called ‘Freezer Burn’ and that song turned out really good, so we did another song called ‘Kaboom.’ We were playing the songs back, trying to figure out who to give them to. So I said, ‘As far as the labels are concerned, just let them hoes fight over who gets the song.’ Everyone was like, ‘Jim, that’s a great song title!’ And in like 20 minutes, we had that song with Lady Gaga.

Trina came into the picture later. “Trina heard it, loved it, and recorded it. It’ll be a single on her album (Amazin'). I don’t know if Lady Gaga is going to be featured on it or doing background vocals, but they are working it out now.
