Ha, Madonna also disagrees. I could see your point if KISS and the Crue ever made songs that sounded alike, videos that looked alike, and similar stage attire outside of leather pants.
Gaga makes me appreciate Alicia Keys in that she can rest in making good music without the desperation of becoming a sex symbol or trying to be like another artist.
"Madonna does have writing credits on all her songs, according to
Metro UK, and wrote several all by herself.
The contention between Lady Gaga and Madonna goes way back. Gaga has faced multiple accusations of ripping off Madonna. Her "Judas" video was considered similar to the video for "Like a Prayer," several fans have
claimed that "Perfect Illusion" resembles "Papa Don't Preach," and Madonna herself
told Rolling Stone that "Born This Way" sounds suspiciously like "Express Yourself."
But she did still consider Lady Gaga "a very talented singer and songwriter," which may be more than Gaga can say about her."
