Hurtwou of Jpopmusic posted the above pic what seems to be a screenshot of the 1st GAM~Amai Yuuwaku~ limited edition DVD. Although there is no source stated, it seems pretty legit. You will notice that there is an Aya version and Miki version of Melodies in addition to the dance shot version of Lu Lu Lu. These seem to be PVs although I don’t remember them having any shots apart in the original, so who really knows.
The CD will be released on May 23rd and will retail for 3,150 yen while the limited edition (with bonus DVD) can be purchased for 3,780 yen. If you would like to preorder the single you can find links to online retailers below.
