A critical backlash began over the repetitive nature of his lyrics, his clean-cut image, and his perceived over-reliance on sampling others' entire 
hooks for the basis of his singles—criticisms also directed to his contemporary, 
Vanilla Ice. He was mocked in music videos by 
3rd Bass (including a 
rap battle with 
MC Serch), 
The D.O.C., DJ Debranz, and 
Ice Cube. 
Oakland hip-hop group 
Digital Underground criticized him in the CD insert of their 
Sex Packets album by placing Hammer's picture in it and referring to him as an unknown 
derelict. 
Q Tip criticized him in "Check the Rhyme," asking, "What you say Hammer? Proper. Rap is not pop, if you call it that then stop." 
LL Cool J dissed him in "To tha Break of Dawn" (from the 
Mama Said Knock You Out album), calling Hammer an "amateur, swinging a Hammer from a bodybag [his pants]," and saying, "My old gym teacher ain't supposed to rap.", though this could have been seen as a response to Hammer calling him out in "Let's Get it Started", when he was mentioned along with 
Run DMC and 
Doug E Fresh as rappers that Hammer claimed to be better than. (LL Cool J would later compliment and commend Hammer's abilities/talents on 
VH-1's 
100 Greatest Songs of Hip Hop, which aired in 2008). However, 
Ice-T came to his defense on his 1991 album 
O.G. Original Gangster: "A special shout out to my man M.C. Hammer: a lot of people dis you, man, but they just jealous." Ice-T later explained that he had nothing against people who were 
pop-rap from the start, as Hammer had been, but only against 
emceeswho switch from being hardcore or dirty to being pop-rap so that they can sell more records.
