Macross F, AKB0048 Recommendations
Both animes use music, singers and idols as a way to fight in the world that they are living in, whether it is to survive or for power/hope.
If you like space drama both are good. Though Macross is much better, AKB0048 might be up your alley as well. Both feature female singers who entertain in order to make a difference in the lives of their audience. As such, there is a lot of insert songs in both anime.
-the art styles are very alike
-engaging story although Macross Frontier is definitely more deep
-use of music and mecha involved
Similar storyline about humans traveling in space and the characters use power of music to help fight their enemies. Also the co creator of Macross and designer of Macross Frontier is working on this.
