I think I'm going to call a song one of my friends likes lame
Why do you want to point something out like that?
Yes, I do not respect their taste.
You shouldn't be so harsh on your friends music tastes!  Remember, taste is subjective.  Let them enjoy what they enjoy!
Who cares? I'll be right, they are just a bunch of losers.
It does not sound like you want to be friends with them if you do that. I think that they are going to get hurt if you insult their musical tastes.
