I feel that this anime is very similar to K-on. ( MUSIC + SPLICE OF LIFE)
Concepts - A School Club that have trouble to be officially made as the club has not met the expected number of members.
Friends of the Protagonist join the club and others as well and they get officially made as a club.They start off as a doubt and unpopular, but work together and have fun and soon become very popular at the school
Genre - Both are about music, One being mainly about School Idols and singing and the other being about a Music band with Guitar,Bass,Drums,Singing.....
Characters - Honoka (Love Live) & Yui (k-on) Both are clumsy and are lazy.
Both very enjoyable - I would prefer K-on more that Love Live IMO, To me it seems to have better feelings
