Over the last 15 years, Eminem has recorded dozens and dozens of memorable guest verses for other artists. From his jaw-dropping bars on Missy Elliott's 2001 track, "Busa Rhyme," to his show-stealing stanzas on Jay Z's 2001 classic, "Renegade," Slim Shady has saved some of his best work for other artists' songs. But he's also provided plenty of heat for his fellow Shady Records rappers as well. Since founding the Shady label back in 1999, he's blessed acts like D12, 50 Cent, and Obie Trice with features and helped Shady sell millions of albums in the process.

Which of those guest verses reign supreme, though? Shady Records is celebrating 15 years in the game in 2014. So to help mark the momentous occasion, we collected The 10 Best Eminem Guest Verses on Shady Records Releases. He may have been a guest but Em sounded right at home on these Shady projects.
