"Tunes & Trials" is the 19th episode in Season 2 of Austin & Ally and the 38th episode overall. It aired on July 19, 2013 from 7:30 PM EST to 8 PM EST. This episode was the twentieth episode to be filmed of season 2. It earned 4.103 million viewers on its premiere night.
Austin writes a song about a girl and after it becomes a musical sensation, fans begin to question who it’s really about. In response, Val sues Austin, Ally, Trish and Dez, claiming that the song was stolen from her newest artist, so did not withdrew her claim and the matter heads to court where the foursome decides to represent themselves. Meanwhile, Trish and Dez use what they've learned from their favorite show, Crime & Judgment, to find out for whom Austin wrote that song and to clear his name.
At the beginning of the episode, Val comes into Sonic Boom to visit Austin and Ally; she wants them to write a song for her to use so that her Stray Kitties can have their first big hit. They decline--they are too busy with their careers, and they do not want to write a song for the woman that could have provided Ally with a major setback--and Val leaves, infuriated. Meanwhile, while writing their latest song, Ally provides Austin with another opportunity to write lyrics--after a bit of persuasion and a bad sports analogy, Austin decides to try writing another song. Ally even buys him his own song book, and gives him advice on what to write about.
Four days later, on the same day that Trish and Dez finish watching all 182 episodes of Crime & Judgement, Austin comes in with the news that he finished writing lyrics to his latest single. And despite Trish being a bit uncertain about his song being any good, it ends up becoming a hit song that is played on the radio a lot.Later on, Val comes back and announces that she has sued them, claiming that Val wrote the lyrics to Steal Your Heart. They go to court, and for most of their time there, despite the efforts of everyone, they are not very successful and it seems like Val will win the case.
Trish then has Austin perform his song as a way to solve the case--after he performs, Trish deduces that the song is about Ally, since she was the only one out of the four suspects that he did not 'flirt' with. She is right; Austin says that she told him to write a song about someone that he cared about, and so he wrote a song about her. The judge then says that he believes Austin after having seen him perform the song as well as talk about his inspiration with Ally. Val tries to convince him otherwise by bringing back up the briefcases; the judge says that the briefcases could have been swapped, as seen in episode 73 of Crime & Judgment. The judge then has Austin continue to show evidence in the form of Austin performing the new song.
Meanwhile, Trish and Dez try to figure out who the song Steal Your Heart is about. They think it could be about Brooke since Dez saw Austin give her flowers at school; Austin, at court, then reveals that he simply returned the flowers that Brooke gave him. Another likely candidate was the European Super Model, since Dez saw them say 'I love you' to each other near Mini's; Austin explains that he has been giving the model English lessons. They also think that the song is about Kira since Dez saw them talk about a secret that they had; after being persuaded, Kira admitted that they did have a secret, but that they had been trying to get Maroon 5 to play at Ally's surprise birthday party. At the end, Austin reveals that the song is about Ally, though.
