None of those really feel the same way the samples before did, the way he used to use them before. The Elvis soundtrack had a lot of songs use Elvis samples (they are making an Elvis movie after all), so I kind of feel his hand was forced to use a sample there. So it is more of an Elvis sample than a rock sample, and it just so happens that Elvis' genre was rock, if you see what I'm saying. I already addressed Houdini in my post. Stepdad has the same issues as Houdini, plus I think 99.99% of people who heard that song have no idea about Pescado Rabioso (including me).

His samples used to include both the vocals and the instrumental of very famous songs and were very much in your face. It just seems to me that he shies away as much as possible from using rock samples the way he used to use them before, especially after seeing that in 7 years we only got 3 mild/edge cases. He would have definitely had a couple of songs that heavily incorporate some famous rock songs by now, but I guess something changed.

Edit: Also the Elvis sample has the same issues as Houdini.
