Will only post intro its pretty long:
INTRODUCTION
Every day in various circles of the music business, this question is asked – what makes the DJ/PRODUCER (“DJ ARTIST”) the artist of a song where there are vocals sung, written, and performed live – in some instances – with the DJ (whom as we will discuss below, often times doesn’t even compose, produce, or play even one note of the music himself)???
In order to answer this question, we have done extensive research on the subject and interviewed Star DJs (Joachim Garraud, Tocadisco), Producers, Singers, The men behind the scenes (“Ghost Producers”), and those who have interviewed them previously to confirm any irregularities.
What you are about to read is something that we all suspected for years (e.g. MLB Players used steroids), but didn’t have the hard evidence to back it up.
We have unearthed articles with damning evidence, and thereafter spoke people such as Joachim Garraud & Tocadisco to confirm our suspicions, as well as have spoken to the journalists whom have interviewed
Nonetheless, prior to getting in to the meat and potatoes, let’s take a step back and review the history and evolution of The DJ/Producer, from an early hit instrumental composition (Robert Miles) to an international pop star in David Guetta, whom is, at best, a “Puppet” and “Puppet Master” says Roman Böer (aka TOCADISCO) similar to Milli Vanilli.
Finally, out of fairness to Mr Guetta and Mr. Garraud, they have issued a formal reply which we have included... However, we must note that we in now way have been able to independently verify the claims made by Garruad in his new response, and are here to simply report all sides and let you, the reader, make the decision on what you beleive to be true.
