I’ve been warned a few weeks ago (many actually…) of a problem with DAS : the extension was able to catch the name of a song played on Deezer and to display it on the status bar, but not to send it to Last.fm. I checked myself and faced the same problem, however I couldn’t find the time to figure out what happened (although it is a matter of minutes) at that time.
Now, as I wanted to (finally) fix this, I was surprised to see that it’s working again (I checked on two distinct machines). Last.fm people are currently working on the API so perhaps a change made my calls go wrong for a while… Anyway, if you still have a problem with the communication to Last.fm (or anything else) : please send me a mail describing what happen or don’t happen (including DAS-related messages in Firefox’s error console).
A word about that : please do not write some kind of bug report/request on the extension’s page on AMO : I don’t receive them as mail, I don’t go check the reviews and most of all, it is not the right place to do so.
Instead, please write directly to gliss-at-acadis-dot-org instead or (better) fill a detailed bug report on the repository at Github : http://github.com/gliss/das/issues.
I must admit also that I almost don’t use Deezer anymore so I am not aware of the problems by myself. Besides, as living in Canada, I don’t have access to many sites like Jiwa.fm. I am mainly and massively using Grooveshark.com which is (in my opinion) way better than Deezer… along with the classical channel at Radio-Canada.
The best way of scrobbling Grooveshark would be to parse the “recently played” RSS feed if you have an account, however I don’t think it should take place in a Firefox extension, a small daemon or even a webapp would do better and much simpler. If there is another way that integrates well in DAS, well, I’ll let you know !
