This, in my opinion, is the best song to introduce people to the band. It references Anne Frank.
Early 00's had a new trend in rock music, something labelled as "Garage Rock Revival" (a not accurate term), started by The Strokes and The White Stripes in the US. The first UK band to emerge from this were The Libertines. Combining influences from every alternative genre since Punk, their style can be felt in every "indie" band to come out from England after them. And that's just to give you an idea of how good they were.
Sousuke Sagara, a 16 year old mercenary, who has lived all his life fighting in various wars. His next mission? To protect a high school girl. This anime combines elements from different genres to create something very enjoyable. There's action, mecha, comedy and some romance, so you'll definitely find something you like.
And the other main aspect of the show is the relationship between Sousuke and Kaname Chidori, the girl he must protect. Sousuke always takes things literally and can't seem to understand everyday logic. Chidori is short-tempered, so she always ends up yelling at Sousuke for his abnormality. But as they grow closer they start to slowly understand each other.
Besides from the two main ones, you find Sousuke's co-workers and a clumsy girl around his age who happens to be his captain.

Electric Light Orchestra (or just ELO) appeared in the 70's. They blended regular rock instruments with an orchestra. Originally, they wanted to continue taking music in the direction the Beatles left it, but they had to give up on this after two albums (because nobody can manage that). That doesn't mean they became worse. In fact, one of their songs was one of John Lennon's favorites.
