Deletion of CollXtion I

Comment: Thank you for edifying. I removed it and tidied other references. On the Catch article as well. Though I would like to ask, why is that not ok? That is a primary source I used to indicate who the producers were on a song. This is from Allie X herself. The  just says not to interpret and to use caution when using primary sources. Why was that wrong
