Fantasia X is the eighth extended play by the South Korean boy group Monsta X.

Light, breezy pop ('Beautiful Night') nestles beside sensual, bassy funk ('It Ain't Over'), the record's middle section reinforced by the commanding brass and EDM of 'Chaotic' and a thumping party track – 'Zone'".

'Stand Up' is "a confession of pain experienced but also a rallying cry to prevail" and "beneath its bouncy, trop-house beats" is a song that "reflects the band's journey through dark places to emerge on the other side".

[10][11] The track "Stand Up" also appeared on the Billboard World Digital Song Sales chart at number 25.

[11] It did not appear on the weekly Gaon Digital Chart, though it appeared on its component Gaon Download Chart at number 102, alongside the other five songs on the EP, with "Flow" at 99, "Zone" at 104, "Beautiful Night" at 106, "Chaotic" at 112, and "It Ain't Over" at 115.
