Because for me that's just opinions.
For example: on the other day around here on atrl, Alexis Jordan CD was sooo shaded and people weere like saying the album is a dissapointment, while I think it's an incredible album. For me, what critics/people say doesnt influence me
They help me find out new music, as some ppl said in this thread before. They are quite knowledgeable and usually have valid opinions about what is great or ****, even when I disagree with them. They don't get paid for nothing after all!
