WOW..... I got a BluRay player about a month ago that has the built in wifi from Sony. I noticed that it had some internet radio streaming stuff for it (along with all that NetFlix stuff) and I gotta say, this Slacker radio I can stream off my Blu Ray player is nothing but win. The player can also do Pandora and NPR.

Back to Slacker, it has about 20 main genres of music and each genre has 10-10 sub-genres for specific tastes. I have been really into the 80's Metal and Old School Hip Hop sub genres. I have done a little with the 90's rock, alternative, and "rap."

Today I had tunes from
Kool G Rap and DJ Polo
KRS ONE
Whodini
Sir Mix a Lot
Mantronix
Salt N Peppa
RUN DMC
Piblic Enemy
Audio Two ( heh...Mc Milk )
Kool Moe Dee
Boogie Down Productions
2 Live Crew

On the Classic Metal
Queensryche
Pantera
Metallica
Megadeath
Guns N Roses
Judas Priest
Motley Crue
.....


They do a good job of variety and mixing classic tunes with lesser known tunes.
