Where have all the rappers went?

Where did all the good artists go? Where are all the songs that you know word from word? I don't know, it seems like the music now is not hot. Anybody can be a rapper or singer now. Who can really sing? Not many artists. Who can really rap? Not many rappers. People are just putting weak music and lyrics out. If the song is hot like from Luda, Mike Jones,Ms. Keys, it takes years for the CD to come out. What's up with that? I loved the old R.Kelly, TLC, Dru Hill, etc. If anybody know some good music please let me know.
