The sad fact of K-pop is that it's oversaturated, and many, many of the groups are definitely over looked. There are so many talented idols that just don't get the spotlight that others do. Some of the success for idols is because of the label, from their producing and promoting, but some of it is just based on pure luck. Most idols are talented and good looking and funny and whatnot, but some just don't make it.
