I have recently installed Spotify. This is a great music service and I immediately purchased the premium account and no other music service gives me this much music for such a great price. I have used meemix.com and last.fm for quite some time, and I really liked the concept of creating your own radio station based on and artist or song.

But Spotify merges the funcitons from a music store like iTunes with the other streaming music services perfectly. In Spotify you can look up your artist, sort and play them by entire album. You create playlists and access them from any PC where you can have the client installed.
I have the client installed on my main PC at home, my Media Center PC in the living room, my office PC and my Asus 1000H Netbook.
Spotify's goal is to let everyone listen to whatever they want, whenever and wherever they want. And I look forward they get mobile platforms up and running. If Spotify manage to establish themselves as a big player in online music distribution they will probably be able to make the needed agreements with the music industry, as well as the manufacturers of portable players, to allow the users to transfer music to their MP3 players for offline play as well.
If so, they have a chance to become a 3rd party version of the Microsoft Zune service, where you for a monthly subscription can access the entire music library on your PC and your Zune portable player, but if you want to transfer music to CD's or further you have to purchase the album/song. This is what I think Spotify should become, but without the connection to only one brand of players, and hence be a better service than Zune which doesn't seem to come out in Europe anytime soon.

But I have a Spotify mystery. I am not yet totally familiar with the technology behind it, but as a new user I use the Radio service in Spotify as well as looking up artist for my own playlists. This radio service is much the same as Last.fm, but you can tick of the genres of music and the range of decades you want it to play random music from. When I select HipHop from the '00 that is what I get.

But when I select Pop from the 00's it's a different picture. The first song suggested is either Cliff Richard or Zombies. And skipping forward gives an endless stream of Cliff, Connie Francis, Lulu, The Righteous Brothers and so on. All these albums have publish dates later than year 2000 but this is not what I was looking for.
Extending the area to 90-00's doesn't seem to help. I end up with listening to "Golden Oldies" only.
Is it me? Does Spotify think I am a Cliff Richard person? I do not know how the mechanics behind it works here. A search for Rihanna, Pink or Brittany Spears gives me most of their music, but the do not appear in Pop radio from their period.
Anybody with the same experience or somebody who can tell me what's up with my Spotify account. I can't take any more Cliff Richard.
