Great internet radio station
This is not a question, but a pointer to a great internet radio station where you chose what they play (and it is free).
It is called PANDORA (www.pandora.com)
You create a radio station for any artist you want to hear (pop, rock, jazz, easy listening etc) and it plays songs by that artist, and other similar artists.
You can set up as many stations as you want, each one playing songs by that and similar artists.
So you could have an Oasis station, Coldplay station, Beatles station, Led Zepplin station, Frank Sinatra station, Miles Davis station and so on.
You can play songs from an individual station, or ask it to play songs from more than one and mix them around.
If you dont like a particular song you can click on it to say you dont like it and it never plays it again. So it learns from your listening habits.
Once you get fed up with one station you can easily jump to another.
I listen to it all the time.
