Apologies to those of you who still don't have access to Spotify - it's a most fun service, and hopefully they'll sort out the licensing for the rest of the world soon.
But for those of you that do have access, here's a link to a playlist of some of my favourite bassists that are also on Twitter:
The list includes me ( @ SoloBassSteve ), @jeffschmidt, @johngoldsby, @ janekgwizdala, @toddjazz and @tripwamsleybass
enjoy! ...if you do enjoy it, please a) share the list and b) thank the musicians on twitter - it's what it's there for :)
