Music Mania 3

 , also known by extension as All Together Now, is the third season produced and second season to air in the Music Mania series. Season 3 was the first season to contain a casting twist, with all acts in the season being groups. The series featured 15 new acts battling it out for their spot in the Hall of Maniacs.

Format
Season 3's format remained largely unchanged from the format of Music Mania 2. Each round, the acts are given a theme to submit for. After all acts have performed, Katy Perry, Shakira, and Lady Gaga rank the performers from best to worst. The best act is declared the winner, with the worst acts being placed in the bottom. It is then required of the winner to give one of the bottom acts the cut and eliminate them from the competition. The cycle continues until only four acts remain, where one artist will earn a spot in the Hall of Maniacs and a recording contract with Capitol Records.

The third season also brought back Wild Weeks, a twist first used in Season 2. The judges' save was also brought back, but the judging panel was given two saves instead of one. It is rumored that there will be a new finale format, but this is only speculation at the time being.

Themes
1= Spooky Introductions “This week is relatively simple. We want a song that introduces what type of artist your act is. Take as much creative liberty as you’d like with this theme but give us a song that you could play for a random person on the street and introduce to them who your act is! First impressions aren’t everything but they certainly will be important.” |-| 2= Ancient Evil “For your second theme, we want you to give us a song that screams nostalgia. Provide us something that sounds like it came straight out of the past!” |-| 3= 7 DEADLY SINS It's time to revisit this iconic theme from S1! However, it'll occur a little bit differently from how it worked before. As you may notice, your team has 7 members, and wow, there are 7 sins! For this week's theme, you'll have to work with your team to assign one of the deadly sins to each performer within your team. So to summarise, one person from each team will submit for either Lust, Gluttony, Greed, Envy, Pride, Sloth and Wrath. You're free to use explanations to your advantage, as long as your submission relates to your assigned sin! |-| 4= TBA |-| 5= TBA |-| 6= TBA |-| 7= TBA |-| 8= TBA |-| 9= TBA |-| 10= TBA |-| 11= TBA |-| 12= TBA |-| |-|
