FineTune – online music playlists
Finetune (http://www.finetune.com/). Now this awesome.
It offers so many good things. However unlike Blogmusik it is not hampered by any of the problems (looking back quite major ones), that Blogmusic suffers from.
The Search facilty is awesome. Granted they may not have every song, but they do offer shed loads in its vast net of music from the Good the Bad and the Queen, Kingdom of Doom to the Cult, She Sells Sanctuary (what a Tune that is).
They offer all the gear, Stations, search other playlists, a social networking element (Every Tom, Dick and Harry seem to offer “social networking” of some form these days – Can anyone be bothered anymore?), comments on songs, tagging etc etc. The list goes on and on
Easy to use, awesome features, and I love it

Great post. Glad you like the service. I’m part of the team that helped build the music player on the site. Just in case you didn’t know, Finetune is also the first music service to explore devices: we just launched a version for the Nintendo Wii – http://www.finetune.com/wii
