When Gaga's song came out in May last year, Madonna said: ''I thought what a wonderful way to redo my song". I mean, I recognized the chord changes. I thought it was... interesting.'
She also told Cynthia McFadden on 20/20: 'When I heard it on the radio, I said "that sounds very familiar". It feels reductive.'
But Gaga defended herself and retorted: 'That's retarded. If you put the songs next to each other, side by side, the only similarities is the chord progression.
'It's the same one that's been in disco music for the last 50 years. Just because I'm the first f****** artist in 25 years to thinking of putting it on Top 40 radio, it doesn’t mean I'm a plagiarist, it means I’m f****** smart. Sorry.'
She said" It sometimes makes people feel better about themselves to put other people down or make fun of them or maybe make mockery of their work,' she told the audience in between songs.
