And just for that, I'm gonna include "Rain Man" by Eminem off his 2004 Encore album. Legendary Slim rhyme flow over a legendary head-bobbin' Dre beat. The song was never a single and didn't generate radio play, but is my personal favorite track on that album.
And there's a personal fond memory of this song. I was at my cousin's 13th birthday party. Brothers and cousins filled the house. We were in his basement playing pool and had this album playing. This song came on. My 3-year-old son started bobbing his head to it, so we focused on him and encouraged him. On the first hook & last bar, it goes "My new name is..." *pause* "Rain Man" and my son mouthed the words "Rain Man" along with it. The whole group erupted in glee. On the second hook, "My new name is..." [everyone looked at my 3-year-old son] and he said out loud "Rain Man" along with it in perfect timing. [eruption of cheers and high fives] It became a phenomenon. Everyone had such fun with it that we immediately played the song a second time and my 3-year-old son stole the day.
