Scrobbled Tracks Disappear (multiple platforms)

  • Problem
  • Updated 4 years ago
For the past few days, when I play and scrobble music continuously for hours at a time, last.fm drops at least 50% of the scrobbled tracks. Often last.fm shows a track while it’s playing, then deletes it from “Recent Tracks” after it has played. Whazzup. Scrobbling from Spotify via MacBook Pro running OS X El Capitan (10.11.4). But apparently this same thing has been happening to iTunes users and Android users, per recent posts from users of those platforms right here at getsatisfaction.com. So clearly it has nothing to do with Mac OS, or Spotify, or Android, or iTunes ... it’s a Last.fm software bug, introduced in a recent update. Please acknowledge and let us know you are working on a fix. Thanks.

If this was a last.fm issue, it would affect all scrobblers but mine is still working. This screenshot was taken a few minutes ago showing my profile. You can also see my media player has a Console window which shows all the output from my scrobbler script.

edit: just to clarify, the bit about old/new values is my local database which is updated after fetching updated playcount info from last.fm.

Thanks for reporting this zeldman, this is your account, right?

Can you tell me are you using the Spotify desktop client or the Spotify web player?  Does this happen with any other scrobbling clients you've tried?  

To clarify what you're seeing: when you start tracks you see them under Recent tracks - the yellow bar with "Scrobbling now", but only about half of them end up in your library here - is that right?   Is it random? i.e. If you replay the same album or set of tracks, do the same ones scrobble, or is it different?  Do the tracks appear at a later time (e.g. are they being cached, and submitted later?).

Finally, can you point out in your library roughly where this happened / what the missing tracks are?  I can see from your library you scrobbled the first half of this album, is that what you're referring to?  


>>> So clearly it has nothing to do with Mac OS, or Spotify, or Android, or iTunes ... it’s a Last.fm software bug, introduced in a recent update.

It's possible... however, so far we're not seeing anything in our graphs to indicate a widespread problem (I have asked the team to check, just in case though).  From what I understand, Apple have just released an update to iTunes in the last couple of days,  and likewise the android app has it's own set of known issues + google play music was updated recently, so I don't think we can rule out client specific issues at this stage.

It's worth pointing out these are set by the client making a call to the track.updateNowPlaying method - usually as soon as playback begins. This notification is in no way related to the actual act of scrobbling so when it says "scrobbling now", it really isn't true until a second call to track.scrobble is successfully made.

track.scrobble should only be called when enough of a track has played for it to count. According to specs, this should happen either half way through the track or at 4 minutes (for any track longer than 8).

It would appear this is the part that is failing for the OP. Without some sort of logging in the client, it's very hard to troubleshoot!

Thanks for responding, Jon!

-- Can you tell me are you using the Spotify desktop client or the Spotify web player?  Does this happen with any other scrobbling clients you've tried?  

Has been happening on Spotify desktop client on Mac OS laptop.

Interestingly, after reading your note, I switched to the Spotify app on my iPhone, and checked the results in the "Scrobbles" app on my iPhone. All the tracks were correctly Scrobbled. So possibly the problem is limited to the Spotify player in my laptop, or a bug in the laptop's operating system.

I'm finishing some out-of-town work now and heading back home. Will let you know if the problem "resolves itself" when I'm able to stop using the laptop and do my normal listening and Scrobbling via iPhone, iPad, and desktop (not laptop).

To answer other questions:

-- Thanks for reporting this zeldman, this is your account, right?

Yes, sir!

-- To clarify what you're seeing: when you start tracks you see them under Recent tracks - the yellow bar with "Scrobbling now", but only about half of them end up in your library here - is that right? 

Yes!

-- Is it random? i.e. If you replay the same album or set of tracks, do the same ones scrobble, or is it different?

It is random.

Thanks for clarifying zeldman.  Please let us know how you get on when you return back home -- it would be helpful to determine if the issue persists on your home network, and if it's limited to your laptop.   I'm not aware of any issues with the Spotify desktop client (if you'd said web player that would have most likely been it), and (at time of writing) you hadn't updated to 10.11.5, so it seems unlikely that your OS would be the cause here.

Hi. Scrobbling from both Spotify and iTunes appears to be working normally and correctly from my various home set-ups. Was working correctly in 10.11.4 and seems to still be working correctly in 10.11.5 since upgrading yesterday. Whether tracks are from Spotify app on phone, Spotify app on iPad, Spotify app on desktop Mac, or new iTunes (12.4.0.119) on desktop, all Scrobbled tracks show up on last.fm and *stay* (they do not delete themselves, as was happening last week over laptop). Can't imagine what the issue was/is with laptop, but will update laptop before next use, and test again soon. If laptop issue continues, I'll add details to this thread that may enable us to troubleshoot. Thanks, Jon.
