A always was a fan o madonna, but that is in the past.
Why is that? You don't like Madonna anymore?
Madonna has had a social-cultural impact on the world through her recordings, attitude, clothing and lifestyle, but the is outdate now.
That is true, but a lot of people still know her and can appreciate her these days.
I am aware she is s known for pushing the boundaries of lyrical content in mainstream popular music.
She is! And she's a strong feminist which is awesome as well.
I respect the fact that she, throughout her career,  has written and produced most of her songs, with many of them reaching number one on the record charts. 
That is really respectable, most artists these days just have somebody else write their songs
Madonna is often cited as an influence by other artists
