Each song has a video of it on an Official Album, right?

Actually, first of all, i never purchased an album. Im a music lover, but just download-and-listen kind of so thats why, and about albums, i never tried to spend my money on that (and i surely dont want you to judge me for not being a musician supporter haha) so i just went online to spend some money and, finally, buy an album (MMLP2) but each website i went to has its AUDIA CD with like 20-25$ and i was with like WTFace! They dont even have a single video song of like Monster or Rap God. I mean, each songs of an artist has a video of it on an official album, right or wrong? but i actually cannot find the VIDEO CD of that album online, or they just record videos for some songs to hit the music channels, correct me please?
