How did the Dazzlings restart their singing career after losing their magic?

Sonata: Dag, I didn't wanna say anything in front of everyone at the party, but you had a little wardrobe malfunction when you were talking to that producer guy.
Adagio: I know. That nip-slip was on purpose, idiot.
Sonata: Oh ... why?
Adagio: Ugh, I can't deal with this tonight. You explain it to her, Ari. I'm gonna go take a shower.
Aria: Adagio got us a record contract with that stunt, numbnuts.
Sonata: Oh! Why didn't you say so in the first place? So she went into that backroom with him to give him a private audition and sign the contract, huh?
Aria: ... Sure, let's call it that.
Sonata: Shouldn't we have all been in there, then?
Aria: I'm sure he would have liked that.
Sonata: ???
Aria: Ugh, just go to sleep, Sonata.
