# track.scrobble

Used to add a track-play to a user's profile. Scrobble a track, or a batch of tracks. Tracks are passed to the service using array notation for each of the below params, up to a maximum of 50 scrobbles per batch [0<=i<=49]. If you are only sending a single scrobble the array notation may be ommited. Note: Extra care should be taken while calculating the signature when using array notation as the parameter names MUST be sorted according to the ASCII table (i.e., artist[10] comes before artist[1]). It is important to not use the corrections returned by the now playing service as input for the scrobble request, unless they have been explicitly approved by the user. Parameter names are case sensitive.
