RTÉ 2fm, or 2FM as it is more commonly referred to, is the second national radio station of Raidió Teilifís Éireann (RTÉ). It broadcasts popular music programming aimed at a young Irish audience.

The station commenced broadcasting in 1979 and has undergone numerous name changes and line-up switches throughout its history. During the 2000s, Ian Dempsey and Tony Fenton opted for moves to rival radio station Today FM, whilst 2FM has in turn raided Phantom FM for Cormac Battle, Jenny Huston and Dan Hegarty, with recent additions Colm & Jim-Jim being poached from FM104. Old stalwarts such as Dave Fanning and Larry Gogan were moved to the weekend to make way for the likes of Rick O'Shea and Nikki Hayes, though Hayes was eventually moved off to the weekend herself and Gogan back to weekdays. As part of the expansion of RTÉ's young people's music radio output, an all-music (mostly of the rock genre) sister station of 2FM, RTÉ 2XM, designed for students and young adults, now operates on the RTÉ DAB Multiplex.

Shane Steven Filan (born 5 July 1979) is one of the lead singers of the multi-awarded and successful Irish pop band Westlife. Filan is one of the five original Westlife members, along with other current members Kian Egan, Mark Feehily and Nicky Byrne and former member Brian McFadden.

Filan was born on 5 July 1979 to Peter and Mae Filan, and grew up in Sligo, a busy commercial town in the northwest of Ireland. The youngest of seven children, he has three brothers and three sisters: Finbarr, Peter Jr, Yvonne, Liam, Denise and Mairead. His parents owned a diner in Sligo named Carlton Caf'e located on Castle Street and Shane used to work there as a waiter from a very early age.

Filan attended Summerhill College, a Catholic school, with Kian Egan and Mark Feehily. All three of them participated in a school production of Grease when they were about 12. The Hawkswell Theatre became a significant part of their careers. Filan was a fan of Michael Jackson as a child, and claimed the singer inspired him to pursue a career in music.

The Walls are an Irish rock band. They were formed in 1998 by two ex-members of The Stunning.

Brothers Steve and Joe Wall (previously of The Stunning) returned to Ireland after a two-year failed label stint in London. Their Camden housemate Carl Harms joined the band on guitar and keyboard duties. Drummer Rory Doyle joined soon afterwards. They set up their own label, Earshot Records (later changing it to Dirtbird Records) and recorded and released a string of singles. A remix of one of the album tracks, "Bone Deep", clicked with radio and became a nationwide hit. Many of the songs have featured on a number of TV series and feature films such as Bachelors Walk, Dead Bodies, Goldfish Memory and On the Edge (starring Cillian Murphy).

The Walls heard rumour of a second Slane Castle date for U2 (as the first concert had sold out in hours). They sent four copies of their album to the band. Bono loved it and offered The Walls a support slot. That day the band played to their biggest crowd to date – around 80,000 people. "To the Bright and Shining Sun" was their next single. That June they supported Red Hot Chili Peppers. They spent the next year gigging while building their own studio in Dublin.
