featuring woohoo

there is a certain tune getting a lot of air play at present which has got me thinking, what does it take to be considered a featured artist?

it seems of late that to lend any amount of credibility as a female artist to your current release there needs to be a reasonable amount of featured artists on a track. obviously not the entire album, that would then be a collaboration and you want it to appear that you did this whole thing on your own...

surely to count as a featured artist you should have to give a little more than standing on the sidelines of some music video looking hard and you should have more lines on the track than a featured extra in a movie?

how then does a simple 15 words that run much shorter than the chorus, woohoo, yeewoo, woohoo, count as anything more than a backup singer? it is simply to easy these days to gain credibility as nothing more than a name and then make the featured artist on a track list...
