They are commenting about another character's taste in music, more cheeky rather than offensive, at the moment I have them describing it as 'lame' and saying that it 'sucks' which would probably be the slang I would hear used, but I am based in the UK and rarely interact with anyone under the age of 18. I just want to know if that would be believable terminology they might use, or are those terms hopelessly dated, if so what suggestions would you have?
Thanks in advance
