yes the 97,000 fans who bought it so far.
if the song only suits the fans, that's not really getting the music out. the purpose is to get it out to the general public as well so even people who might not like J.LO will like the song chosen and buy the album anyways. If it's just for the fans...I mean come on.
And I think labels give up because they aren't making any money. and if the album is a flop, a very bad flop like Jenny's, there is no point to continue wasting money from their money bank on something that seems like it will never redeem. it's all about money.
