"Listen to ten of our favourite new songs below, including Britney Spears, Aiden, Lady Gaga and Katy B. Britney Spears: &amp;#039;Perfume&amp;#039; (out now in the US) It&amp;#039;s not often that we get a ballad from Britney Spears; so when she does decide to put one out, the expectation is going to be high - especially when hitmaker Sia is at the helm. But after the endless teasing from its producers and the woman herself, we&amp;#039;re pleased to report that &amp;#039;Perfume&amp;#039; lives up to the hype; although it&amp;#039;ll take a few listens to sink in.      Aiden: &amp;#039;Satisfy Me&amp;#039; (&amp;#039;Aiden&amp;#039; EP out on November 26) The former X Factor contestant returns sans surname and with a brand new image ahead of his new EP release later this month. Co-helmed by Dimitri Tikovoi (Charli XCX, Mikky Ekko), &amp;#039;Satisfy Me&amp;#039; feels like a natural progression from the slick (and occasionally wobbly) pop of his debut album to a synth-driven sound that&amp;#039;s surprisingly slick.   Lady Gaga: &amp;#039;Dope&amp;#039; (out now) Her new album ARTPOP may have leaked online ahead of its release, but Gaga has pressed on with her latest buzz single &amp;#039;Dope&amp;#039;; an emotional ballad about a tricky break-up told over weighty piano thuds and bobbing synths.       A Great Big World ft. Christina Aguilera: &amp;#039;Say Something&amp;#039; (out now in the US) What Christina Aguilera wants, Christina Aguilera gets. After falling in love with A Great Big World&amp;#039;s emotional piano ballad &amp;#039;Say Something&amp;#039;, the singer insisted that she jumped on the track. The result is one of her most understated outings in recent memory, and it&amp;#039;s all the better for it.       Katy B: &amp;#039;I Like You&amp;#039; (out now) For the B-side of her new single &amp;#039;5am&amp;#039;, Katy B returns to her Peckham roots on &amp;#039;I Like You&amp;#039;. Produced by Berlin garage DJ George FitzGerald, the track hear&amp;#039;s Katy&amp;#039;s vocal effortlessly bounce off late-night house thumps and a hypnotic chorus.  Demi Lovato: &amp;#039;Let It Go&amp;#039; (out now in the US, Frozen out December 6) The singer has recorded a track for Disney&amp;#039;s new film Frozen which, unsurprisingly, is a ballsy, fists-in-the-air anthem about finding the strength to go it alone.       Joel Compass ft. Pusha T: &amp;#039;Run&amp;#039; (out now We wrote about how much we enjoyed 20-year-old Londoner Joel Compass and his alt-R&amp;amp;B song &amp;#039;Run&amp;#039; only a few weeks ago. And given that US rapper Pusha T has since recorded a guest skit for it, we&amp;#039;re guessing we&amp;#039;re not the only ones.   Disclosure: &amp;#039;Apollo&amp;#039; (out now) They may have missed out on last week&amp;#039;s Mercury Prize, but Disclosure continue to push forward with the unveiling of spacious house track &amp;#039;Apollo&amp;#039;, which they told us they&amp;#039;ve put out &amp;quot;purely for the fun of it&amp;quot; and not ahead of a re-release of their debut album Settle.   James Vincent McMorrow: &amp;#039;Cavalier&amp;#039; (out now) The rising Irish singer recently sent hype machines into overdrive with his latest effort, which marks a shift into new sonic territory from his 2011 debut. His second LP Post Tropical follows in January next year.       Chromatone: &amp;#039;Flyin&amp;#039;&amp;#039; (out now) He&amp;#039;s been producing electronic music for over a decade, but Chromatone could well crack the top 40 charts with &amp;#039;Flyin&amp;#039;&amp;#039;, which blends squelchy beats with highly addictive pop hooks.
