For me it was Nct 127's album Neo Zone. It was just filled with songs that hyped me up like "Kick it", "Mad dog" and "Sit down". Songs that were just chill and groovy like "Boom" and "Day dream". Lastly there was "White night" and "Not alone" that made me emotional since I really felt what they were saying since I was going through some hard times and the pandemic really affected me mentally. And lastly, "Dreams come true" was just a wonderful ending to this beautiful album. To me it felt like I shouldn't give up and that one day I will get the happiness after all these difficult paths.
(Also wanna add how BTS's Be album helped a lot especially "Life goes on").
Have an amazing and safe 2021 :)
