A recommendation from someone who you trust for their musical taste, the fact everyone is talking about it or I have a lot of this artist's music so I'll buy another album by them since I know I'll like it !
You put the CD on and low and behold it kinna sucks !!!! You want to listen to the whole album just by some remote chance it grows on you and you end up liking it, No chance it still sucks so you listen but inside you're saying " Hurry up, please get it over with !!! ". Some of you without a doubt will say I listen to the first or a couple of tracks and stop it if I don't like it ! A very unpleasant experience !
I've had several experiences like this (however none from the MD member's recommendations !)
