Listening to the LIT Music Bot, it is playing "Never Gonna Give you up" on repeat, except there's some noise. This is a morse with the longer noise being "_", shorter noise being ".", and the woodblock sound being " ".
._.. .. _ _._. _ .._. { ._. .. _._. _._ .. .._. .. . _.. }
Using an online Morse Code translator (https://morsecode.world/international/translator.html), we get the flag.
Flag: LITCTF{RICKIFIED}
