I also signed up this afternoon, impressions so far are really great. Except for the lack of an iPad App, although a comment from them on their Facebook page said that it being developed and should launch end year.
What still impresses me the most is the smaller labels being included. Epitaph for example. Still and independent label I think, but they have all my teenage years bands signed to them.
Busy creating my first Playlist now which I will then download to my phone. KerPunk
Only thing that I've noticed so far out of the 100 or so tracks I've played is one track from Pennywise, called Bro Hymn Tribute. It was a 8 minute long song dedicated to the bass player who committed suicide. After the 2-3 minutes song, there was a long silence, then a 2-4 minute long piano solo started. The song on Simfy is 8 minutes long, but has no piano solo. Just nothing after the song. Pity, that was still one of my favourite things ever. Thinking the album had finished playing, only to be reminded by the piano solo that it still had more awesomeness left. Guess there will be a few song that have been changed for licensing reasons.
But for R2 a day, I'm in and ready to go.
Used to listen to ShoutCast all day while working, so this is a major upgrade actually.
