ELI5: Explain Like I'm 5

Last.fm

Okay, so imagine you really like music and you want to keep track of all the songs you listen to. That's where Last.fm comes in! It's like a little buddy that hangs out with you and watches what music you listen to.

When you sign up with Last.fm, you tell it what music players you use (like Spotify or iTunes) and it starts listening to what you're playing. It keeps track of all the songs you listen to and creates a profile for you.

Then, based on all the songs you listen to, it makes recommendations for other songs you might like. It also shows you what your friends are listening to and you can discover new music together.

It's like having a friend who always knows what music you like and can suggest new songs you'll love. So, that's what Last.fm is all about!
