Both are about a rock girl band, both are based on famous novels..................................................

"Aozora Yell" tells a story of a high school girl named Tsubasa Ono who saw an inspirational brass band performance at the finals of the Japanese high school baseball championships one summer. Tsubasa vows to join the band when she enters high school, and she happens to meet a certain boy there. ~~ Adapted from the manga by Kazune Kawahara.

On a spring day Munakata Ikujou visited an old temple to view a 1000 years old sakura tree. There Ikujou discovered a 3-year-old girl and adopted her as his own daughter. 16 years later, Sakurako has grown up to become a beautiful woman. Sakurako then has a fateful meeting with Takanashi Hiroto. Their pure love begin.

Both basically in the same brethren - a bunch of kids in school setting doing DIY stuff (Summer Film is movie, Linda is music). The pacing and zero-to-hero plot of both shows are similar.

Another great movie about friendship, girls' music band and girl power!
Last not least, in both some works from Blue Hearts are performed

A behind-the-scenes look at the entertainment industry's PR teams, managers, and reporters as they scramble to clean up the messes created by their stars. Oh Han Byul leads an entertainment agency's PR team. One of her top clients is the star Gong Tae Sung, who can do no wrong. They were in high school and college together, where he became her sworn enemy. They bicker constantly but soon develop feelings for one another.

Music forms an important part of both movies. They have the same laid-back feel, and both are directed by Yamashita Nobuhiro.

Four schoolgirls start a covers band so they can play at the school festival, and have to overcome a tight time-limit and personal dramas before they get there.

Only three days before their high school festival, guitarist Kei (Yu Kashii), drummer Kyoko (Aki Maeda), and bassist Nozumi (Shiori Sekine) are forced to recruit a new lead vocalist for their band. They choose Korean exchange student Son (Bae Doo-Na), though her comprehension of Japanese is a bit rough! It's a race against time as the group struggles to learn three tunes for the festival's rock concert—including a classic '80s punk-pop song by the Japanese group The Blue Hearts called "Linda Linda"...

Aki Miyata was a musician and died 1 year ago. He had a bright and positive personality. Sota Kubota is a university student. He is not good at socializing with people. One day, Sota Kubota picks up a cassette tape, which was left by Aki Miyata. If Sota Kubota plays the cassette tape, Aki Miyata’s spirit takes over Sota Kubota's body for only 30 minutes. With Aki Miyata's spirit in his body, Sota Kubota goes to see Aki's former girlfriend Kana Murase and his other bandmates.
