Elbow and Jimi Goodwin - 'New York Morning': Jimi Goodwin of the Doves provides backing vocals on New York Morning, the fourth track from their latest album, The Take Of And The Landing of Everything. The Manchester vocalists couldn't be better suited to one another and are seemingly an inspiration to each other as each of their separate projects blossom with age.

Sub Luna City - 'City Rivims Mk 1': 'City Rivims Mk 1' is the best introduction to Sub Luna City. King Krule who you'll hear on vocals here provides far more to this project than a fleeting appearance. He's been a vital component in establishing this group.by writing all the beats over which friends Rago Foot, Jadesea and Black Mack trigger and rap over live.

Ratking feat. King Krule - 'So Sick Stories': Ratking are XL-signed teenage MCs from Brooklyn who similarly to King Krule's solo stuff have a sound that seems indebted to the inner city setting. This is their albums highlight thanks to the unique vowelly drawl King Krule provides.

She's back in collaboration with him this year for his next album which is due out in August this year. The teaser they've released switches between dark, delicate trip hop and heavy electronic bass lines. A strong indicator Tricky has made another great album.

Disclosure feat. Mary.J Blige - 'F For You': The Grammy Award winning electronic music duo from Surrey are in high demand when it comes to collaboration. The biggest compliment toward them came when Nile Rodgers announced he was interested in working with them last year. This year they've performed with Lorde at the Brits and made a track with Sam Smith. The pick of their output this year though is this soulful slice of dance music and it cements their status at the top of the electronic music tree.

Manic Street Preachers (feat Cian Ciaran) - 'The Next Jet To Moscow': Manic Street Preachers and Super Furry Animals are probably the most influential bands of a generation in Wales, and to see members of each in a band together makes for happy reading. This pulsating piece of post punk power pop features SFA's Cian Ciaran on keys & noise and is a highlight from the powerful 'Futurology' album, which was released this week.

Tony Allen & Damon Albarn - 'Go Back': One of Afrobeats founding fathers, Tony Allen has had a long standing musical relationship with Albarn.

This year Albarn has provided lead vocal for Allen's composition 'Go Back'.

Chris Martin and Cat Power - 'Wish I Was Here':The title track to Scrubs actor and film director Zach Braff's new film Wish I Was Here features this heavyweight meeting of minds. Outstanding contributors to pop music in their own right, the matrimony heard here emphasises each of their position as prolific songwriters.

He's set up his own eco-friendly pop-up coffee shop Tim Peaks, he's running O Genesis records which has put out some great material from the likes of Slowgun and Hatcham Social. Last year he released a solo album that was inspired by and worked on with Kurt Wagner of alternative country band Lambchop. For Record Store 2014 they released this co-written song, and brought in New York composer Peter Gordon on saxophone.

Lykke Li and ASAP Rocky - 'No Rest For The Wicked': Lykke Li is no stranger to collaborating with top players. She collaborated with David Lynch to release 'I'm Waiting Here' which was one of the most heart-wrenching songs of the year. This year she remixed her album cut 'No Rest For The Wicked' and had ASAP Rocky at the heart of it. The down tempo melancholy of Lykke Li's vocals mixed ASAP's rap work remarkably well.
