daus.....kalo nak lebih tepat lagi pengiraan populariti kat kriteria download tu.....esp utk video youtube....ambil jugak percentage like and unlike also number of comment of that video over jumlah views.....coz views sahaja doesn't mean that video is popular coz ada org masuk tgk hanya utk mengutuk.....atau hanya tgk kerana curious......just a suggestion....
