To which service are you gonna 'scrobble' your data over? Your own? You would need a online platform of some sort in that case. But your question seems a bit vague.
A term used by last.fm. Scrobbling involves taking the last songs you played through your media player (eg. iTunes), and filing away the info to improve, and better tailor the songs that are played for you through last.fm.
After a number of songs are listened to through your media player of choice, a window from last.fm will appear, listing these songs, and confirming that you wish to scrobble them. The user has the option of de-selecting songs that they do not wish to scrobble. - Urban Dictionary
