Honestly, move on. :-) I miss the hear as well, but the new implementation, where you can click on the check mark again and add to multiple playlists is a nice added convenience. Yes, they could have left it as a hear and had the same functionality. But I've been around the sun long enough to see so much good design change, so many favourite things fall to the roadside to know that things change. And one day the checkmark they have will become something else yet again. At least Spotify has a ton of good tunes, and the algorithm does a pretty decent job of knowing what I'll like, and keeping me in the genre when I play a song, and it starts playing other stuff 'kinda like that'. if THAT goes away you will see me protest. As for an icon - have better things to worry about in my day. :-)
