Can you just walk into a studio like Shady Records with demo CD and see if can get signed by record label or beat track producer?

No, you cannot just walk into a studio like Shady Records with a demo CD and expect to get signed by the record label or have your beat track produced by a renowned producer. The music industry is highly competitive, and record labels, along with producers, are very selective about who they sign or choose to work with. Getting signed to a major record label typically involves going through a rigorous process of submitting your music, getting feedback from industry professionals, networking, and building relationships. Similarly, getting your beat track produced by a renowned producer also involves establishing connections, demonstrating your talent and skills, and presenting a compelling and unique sound. It is highly recommended to do your research, get feedback from music professionals, and build your credibility before reaching out to studios or producers.
