::Interesting, I did compare for example Lady Gaga's "Born This Way" and "Judas", and as you claimed on my talk page, the positions both on FIMI and Italiancharts.com correlate perfectly. Thanks for that information, I wasn't aware that Italian Music Industry didn't release Physical singles at all, I guess you learn something new everyday. But I don't believe I have ever reverted an edit that didn't deserve to be reverted. I have reverted those edits of yours, the positions in which couldn't have been verified as you didn't provide any actual sources, see this recent edit of yours. I also have reverted such edits of yours which were based on Fan-collected and unreliable sources, see this here . They both clearly deserved to be reverted, don't you agree? As for my own edits, whenever Italiancharts.com has positions available, that is my first choice. I only turn to charts like hitparadeitalia or acharts.us when the former doesn't have positions available.
