I've had an account at we7 ever since it started in 2008 but never used it much, so I went back and dusted it off. And I like it. we7 reminds me more of Pandora, which I used quite a lot before it barred UK users, and that suits me better than Spotify anyway. I also purchased and downloaded a song, something I could never get to work with Spotify, although we7 is more expensive than Amazon or iTunes.
Chatting with my kids about this at the weekend I got incredulous remarks about why anyone would want to use these services anyway. We've got YouTube Dad. And YouTubeU doesn't charge £9k a year.
