What is the worst/best song in MLP:FiM?

I somehow think some of the songs are quite ridiculous
 
Like.
 
Make This Castle A Home  
The Rules Of Rarity  
I’ll Fly  
The Kart Song
 
The kart song was very ridiculous. I’m talking about the one from last episode.  
Remember? everypony was acting very stupid. They didn’t care about the CmC’s feelings whatsoever..  
I wouldn’t have blamed them.  
Do you remember some of the lyrics from that song?
 
Some of the songs were good.  
The Laugh Song  
Winter Wrap Up  
Gala Song
 
So what are your thoughts exactly…

Best song:  
Smile (obviously)  
Winter wrap up (it kinda sounds like sherbet land from MKDD)  
Celestia’s ballad (we need more celestia songs)  
Babs seed (it’s just so catchy)  
Glass of water (i loved both the song and the episode)
 
 
Worst song:  
The spectacle (it made me cringe)  
Hush now (SB version) at least in the dub that i saw, it made my ears hurt
 
Actually there’s just a few songs that i dislike or hate and in other songs the problem is with the lyrics instead of the melody

I actually like almost all of the songs in the show. Even the intentionally butchered cutie mark crusaders song, which I keep hoping will someday be released in its non ruined form. About the only one I can think of I don’t care much for is Spike and Pinkie’s song about sharing from season 1, and Spike’s attempt to sing the anthem at the games.
