I think there's a big one in how the lines feel to the artist.. sure the rhymes need to be great, and as far as possible clean from clichés, but in the end a song can get chosen for a cut by feel, I think.

Probably not the outsiders songs, though, but the insiders play them for each other, and they are probably played in the artists' audition sessions as well, with their street team as listeners. And a song that feels good for the artist to sing, will come out stronger..

In my experience, many clichés actually sings great, and I think thats a big part of why we keep on finding them in the releases!
