I'm a Die-Heart 팬 on the 메탈리카 spot but... I have no idea how.

Ok so about 3 days 이전 I got the "Die-Heart" medal for the 메탈리카 spot, but I was kinda of surprise I got it so early (Well I knew I was going to get it sooner 또는 later cause 메탈리카 is my 가장 좋아하는 band of all times) but it came VERY early, cause I was just a Dedicated 팬 on there and 4 weeks later I became a Die-Heart 팬 and the most I have added in these 4 weeks was 5 비디오 and that's it... Soo my 질문 is how did I become a Die-Heart 팬 without doing much?
