According to the dictionary definition,
a ura means a adresa cuiva o dorință de bine (to wish well to somebody) so there is no shouting involved here.
A cânta colinde, a merge cu colindul and a colinda do not necessarily mean singing Christmas carols. In fact the verse you’re quoting is from Plugușorul, a traditional Romanian carol for New Year

Side note:
a colinda also means to wander.
Let’s see if you can use this information and come up with a better translation. Good luck!
