Thanks for asking - and its a good question!
My current favourites are Anna Ternheim and Miss Li; both for their distinctive voices and the immediate appeal of their songs, although two more contrasting performers I can hardly imagine.
I enjoy the tunefully strange rock of bob hund, and the various (retro pop?) projects of Henrik Andersson: Ray Wonder, Hank, Vicky and most recently, The Clown.
My all time favourites remain ABBA and Komeda; for their musicianship, charm, and the nice places their music takes me to.
Miss Li - I Heard of a Girl
The Clown - Back to the Root
