But I would say it's more Dannii Minogues songs that are severely underrated

It's in your eyes.

Beat me to it, but I agree 100% with PYIMP. Still think it's an awesome track but maybe suffered to being released in late 1994 up against all the Xmas novelty singles. I reckon an early 1995 release instead would've seen the song make the top 10 on similar sales.

I love 'Do you dare' and 'Closer' from her rave days in the early 90s

This thread is brilliant! I'm a life long Kylie fan but here I've been introduced to songs I never know existed. Thanks, everyone!

Some really good choices. Kylie is someone whose best songs are often left as album tracks or hidden away as B-sides. It's a shame. Her cover of If You Don't Love Me is another favourite of mine. It was great to see her perform it on the Aphrodite Tour.

Have just remembered Skirt, which I really like. Feels like it could have been a big club hit.

Pretty much anything from her Deconstruction phase. I can't be the only person who adores some of her material during that time. Any other fans? I never got why she was less successful in that era. Musically the two album she put out in that time were excellent. I wish the mainstream were more embracing of her change in direction. I bet if she brought out those albums in this era she would've been successful, as artists tend to be more experimental these days.

Put Yourself In My Place
Where The Wild Roses Grow
Some Kind of Bliss (how incredible is this song?)
Breathe
Did It Again

Also, from her 2000 comeback,

On A Night Like This
Please Stay

Completely agree with your entire post especially the bit I've put in bold! Great song. I can see why it might not have been commercially successful, artists do tend to dwindle after a few years of good success, and it was a complete change of direction. Just be thankful her comeback came at the right time and was a success. Its very rare artists maintain success over 3+ decades like Madonna Cher and Kylie.

I think most of the songs on X are pretty underrated. That was an amazing album, far better than Aphrodite but they messed it up with having 2 Hearts as the lead single.

X is a solid album, but it could have been a little better with a few tweaks here and there. Carried Away, Ripping Up the Disco and Cherry Bomb should have been included on the album instead of Nu-di-ty, Heart Beat Rock and No More Rain. I can't complain too much, it yielded three top 10 hits and sold over 460,000 copies in the UK.
