In reply to gio88.

Gaga writes ALL her own lyrics and melodies plus she co-produces her songs, she is a classically trained pianist and has been writing songs since she was 11. She gives co-writing credits to whatever producers she works with because she is generous like that, she even gave Beyonce a writing credit for Telephone! She has never said she does the whole thing by herself, nobody does that, even singer/songwriters need to collaborate with one or more producers, particularly if they write dance music. This is all common knowledge so I have to conclude that you are singularly ill-informed when it comes to Lady Gaga.
