What about Nanatsu no Taizai's two OPs: Netsujo no Spectrum by Ikimono-gakari (who did Bluebird for Naruto Shippuden OP) and 7-Seven by Man with a Mission (The guys who did Database with Log Horizon OP)? They are awesome OP musics too despite the series being new in the recent popular anime list that had yet a second season soon enough.

Just wondering you know.
