The only reason I use last.fm is the scrobbling, I'd love it if they'd focus on music analytics more than radio. The moody pdf report in their playground is amazing.
Same. I switched to spotify (and spotify radio, which is free) a while ago. But I still scrobble everything and it's cool to look back! Not to mention you can do a lot with the data.
Unclear what you mean. They both scrobble, do you aggregate them together someplace?
