Ehhh.....not really. Depending on who it's with and the point they are trying to get across with the song, I may not try as hard when I'm writing it, but I try to put the same emotion and shit into everything I do. If I think the idea is something I can really relate to, it doesn't matter who I'm doing the track with
EDIT
But I'd probably try hard no matter what if it was with someone I deemed as good. Even if I wasn't really feeling the topic....
Wanna collab? lol.
