Delete Tracks from the Last.fm Library from Spotify
After you send a track to Last.fm from Spotify, that track gets added to your Last.fm Library — essentially a database of tracks you’ve listened to. It’s no big deal if you forgot to uncheck the scrobble box when you played “Twinkle Twinkle Little Star” and “The Wheels on the Bus” for your kid because you can go into Last.fm and delete unwanted tracks from your Last.fm Library.
That way, Last.fm won’t keep telling you to listen to The Muppets albums all the time.
Follow these steps to remove a track from your Last.fm Library:
Log into Last.fm, and then go to your Profile page by clicking your username at the top-right of the screen.
Alternatively, type www.last.fm/user/yourusername directly in your browser address bar.
In the Recently Listened Tracks section, hover your mouse pointer over the track that you want to delete.
A gray box with a cog icon on it appears next to the track.
Click this cog to display a drop-down list of editing choices.
Click Remove from Your Library to get rid of the track.
(Optional) If you want, repeat Steps 2 through 4 in the Top Artists and Top Tracks section, farther down the page.
Don’t worry, deleting the track from Last.fm only deletes it from the listening history for your account, not your computer.
