I thought I'd do a little summary of my thoughts on each song off this flawless album.
Warrior:- Such a flawless album opener! The lyrics and message are really inspiring, and I love the breakdown in the bridge.
Die Young:- So awesome, and it's so damn catchy. Such a fun, light-hearted song. One of the weaker ones on the album, but that shows what a good album it is if a song like DY is a weaker track.
C'mon:- One of my favorites! It's such a jam and has such a nostalgic, light-hearted feel to it.
Thinking of You:- One of my top three without a doubt! The chorus is absoloutley flawless, so catchy. I also love the breakdown bit during the bridge, it reminds me a little of Last Friday Night which is why I love it.
Crazy Kids:- Yet another flawless track, The chorus is so catchy and it's definitely single material. The rapping parts are so awesome as well. I love the line "Make the ****ers shake, like an earthquake". Pretty epic.
Wherever You Are:- Not quite as strong as the previous tracks. Still a real jam though and I love the lyrics. If I was to call any of the songs a filler it would probably be this one.
Dirty Love:- EPIC. The lyrics and melody are Pop/Rock heaven, and Kesha's voice sounds so awesome. One of my favorites.
Wonderland:- This sort of song makes me want to go on a summer road-trip or something. It just feels so nostalgic and it's a really pretty song.
Only Wanna Dance With You:- Completely ***** on the demo version. The new lyrics, the guitar solo and the fact that her voice doesn't sound overly auto-tuned like it did on the demo make me love this song. It's such a cute song and could make such an awesome video. Single worthy in my eyes. One of my favorites.
Supernatural:- My favorite. The lyrics, the melody, the breakdown - just everything about this song is amazing. It sounded strange at first, but I've gotten used it to now. I hope this is a single because it would make such an incredible music video. I love the lyric "Till the morning light, watch my silhouette. Don't you know tonight, we're gonna wake the dead".
All That Matters:- This one for me is similar to Wherever You Are, awesome tracks and easy to bop too, but not quite as memorable as other tracks. Still great though.
Love Into The Light:- Incredible. I love the fact it's an electro-ballad, and those drums leading into the chorus are epic. Kesha's vocals sound phenomenal. Probably a joint favorite with Supernatural. It's perfect.
Last Goodbye:- I really love this song. I didn't expect the chorus and it's definitely more poppy than a thought it would be.
Gold Trans Am:- OMG, what kind of slayage? This is without a doubt the best out of the bonus tracks and it puzzles me why it isn't on the album! I LOVE the chorus, it almost feels slightly country-ish and reminds of something like Sweet Home Alabama. Such a nostalgic song and makes me want it to be summer again.
Out Alive:- Such a club banger! ! ! This is such an awesome party song.
Past Lives:- Adore this song. It's so melancholy and sad, yet happy at the same time. I love her voice in this and it's one of my favorites.
That's just a summary of my love for this album.
Sounds like you have some love for every song. That's fantastic 
I wanted something We Are Never Ever Getting Back Together-esque since I think that was a Max Martin + Shellback track as well? It would have fit in with Only Wanna Dance With You, Wonderland, and Gold Trans Am.
