Usually I don't put a lot of focus on the lyrics either, but since their company's youtube channel has the subtitles on by default I happened to see them and I was really into it. The lyrics to N.O. and No More Dream are everything tbh. The lyrics also helped in a sense because I'm not usually into groups that are heavy on hip-hop and rap so it was easy to make an exception in this case (if that makes any sense). The only similar group to them I'm into is B.A.P who are also incredibly amazing. I used to be super into SHINee but I'm not so much recently. To be honest I'm mostly a casual fan of a lot of groups, I mostly pay attention just to Infinite. I'm very, very picky about music I actually like so there are few groups I actually consider myself a fan of.
