Title pretty much sums it up.
Sometimes friends remind me of songs I haven't heard in years or a song I didn't know anyone else liked and it would be nice to acknowledge that without having to switch over to Facebook.
I should just be able to right click on the user/song in the feed on the right and "like" it, or have a "like" button on the feed item itself
Although this idea has been suggested first, I'd like to merge it with a more popular idea, that has a slightly more informative title/description to ensure this idea gets the best attention it deserves:
Add your kudos there please! 😉
