[url id="/ontv/dyn/the_hills/cast_member/cast_member.jhtml?personalityId=11760"]Spencer Pratt[/url] is certainly confident about [article id="1611096"]his career as a rapper[/article]. He's released one track, "I'm a Celebrity... Get Me Out of Here," and he's already four songs into his debut album, Angels & Demons, which he hopes to have out by his birthday on August 14.

He says that by the time his album reaches record-store shelves he should have 12 songs that give fans some insight into what it's like to be Spencer Pratt. "I've been battling these demons, and ever since the angel Heidi came into my life, things have been better," he told MTV News. "Half the album is Spencer Pratt battling his demons and the other half is about me and my angel."

Pratt knows it won't be easy for him to convince people that he really wants to be an artist and that he isn't just trying to cash in on his "Hills" fame. And, in case you're wondering, he reads all the negative comments people leave about him.

"I would say to my critics, they inspire me to keep going even more than the day before, and I read all their posts and comments and it's amazing that they keep hating," he said. "[It hurts] a little bit. I feel like everyone's success is driven off their jealousy and envy."

To prove to everyone just how badly he wants to succeed in the music industry, he said that one day he'll just start giving his music away for free. Why? Because it's about more than making money.

"It's not the money. Eventually the music will be free, and it's because I want people to hear how much I want to make music," he said. "I think I can make tracks out there better than Flo Rida. I'll swoop down on Flo Rida in a second. I'm gonna get myself a 'Right Round.' "
