"Alfie" is a song by British recording artist Lily Allen from her debut studio album, "Alright, Still" (2006).
 Written by Allen and Greg Kurstin, the song was released as the fourth and final single from the album, on 5 March 2007, by Regal Recordings.
 In the United Kingdom, it was marketed as a double A-side single, along with "Shame for You".
 While the melody incorporates a sample of Sandie Shaw's "Puppet on a String", the lyrics directly describe Allen's real life younger brother, actor Alfie Allen, criticising him for his lazy behaviour.
"Smile" is the debut single by British recording artist Lily Allen from her debut studio album "Alright, Still" (2006).
 It was written by Allen, Iyiola Babalola and Darren Lewis, while sampling The Soul Brothers' "Free Soul".
 The song was released as the lead mainstream single of the album in July 2006.
 After signing a contract deal with Regal Recordings and gaining popularity on the social network website Myspace with demo songs, Allen released a limited edition of "LDN" to promote her work and afterwards announced the release of "Smile".
Social media marketing is the use of social media platforms and websites to promote a product or service.
 Although the terms e-marketing and digital marketing are still dominant in academia, social media marketing is becoming more popular for both practitioners and researchers.
 Most social media platforms have built-in data analytics tools, which enable companies to track the progress, success, and engagement of ad campaigns.
 Companies address a range of stakeholders through social media marketing, including current and potential customers, current and potential employees, journalists, bloggers, and the general public.
 On a strategic level, social media marketing includes the management of a marketing campaign, governance, setting the scope (e.g. more active or passive use) and the establishment of a firm's desired social media "culture" and "tone."
CollXtion I is the debut extended play (EP) album by Canadian singer-songwriter Allie X, released physically on 7 April 2015 with a short cell cycle.
 It is her first record released under the name Allie X.
 The EP was initially released on 7 April 2015 in Canada.
 The worldwide release was pushed back twice, once to 14 April 2015 and then to 21 April 2015.
 "CollXtion I" is intended to be the first of at least five CollXtions, each being a unique multimedia experience that will include the spinning GIFs featured in her YouTube videos, a comic detailing an abstract autobiography, and song stems to allow fans to make their own creations.
 She has stated that the EP is influenced by her interest in medicine, psychology, and the macabre.
 During a question and answer session on social media site Tumblr, Allie stated that the overall theme for "CollXtion I" is "addiction and self destruction".
Social media optimization (SMO) is the use of a number of outlets and communities to generate publicity to increase the awareness of a product, service brand or event.
 Types of social media involved include RSS feeds, social news and bookmarking sites, as well as social networking sites, such as Facebook, Twitter, video sharing websites and blogging sites.
 SMO is similar to search engine optimization, in that the goal is to generate web traffic and to a site and increase awareness for a website.
 In general, social media optimization refers to optimizing a website and its content to encourage more users to use and share links to the website across social media and networking sites.
 SMO also refers to software tools that automate this process, or to website experts who undertake this process for clients.
Alright, Still is the debut studio album by English singer and songwriter Lily Allen, released on 13 July 2006 by Regal Recordings.
 After being rejected by several labels, Allen signed to London Records, who eventually lost interest in Allen, leading her to meet production duo Future Cut and sign to Regal Recordings.
 Recording for the album began in 2004 with sessions between Allen and Future Cut, and Allen's work garnered publicity on the Internet as she posted demos to her Myspace account before they were officially released.
 Allen later travelled to the United States to work with Greg Kurstin and Mark Ronson, to complete the final half of the album in 2006.
Lily Rose Beatrice Cooper (née Allen; born 2 May 1985), known professionally as Lily Allen, is an English singer, songwriter, actress, and television presenter.
 She is the daughter of actor Keith Allen and film producer Alison Owen.
 Allen left school when she was 15 and concentrated on improving her performing and compositional skills.
 In 2005, she made some of her recordings public on Myspace and the publicity resulted in airplay on BBC Radio 1 and a contract with Regal Recordings.
English singer and songwriter Lily Allen has released three studio albums, two extended plays, 20 singles (including six as a featured artist), two promotional singles and 21 music videos. Allen's range of musical genres incorporates styles such as pop, ska, electropop and reggae fusion.
 She became well-known through her Myspace account, on which she started posting demo songs in 2005.
 The increase of popularity led to a contract with Regal Recordings.
 Her debut single, "Smile", was released in 2006 and topped the UK Singles Chart for two weeks.
 Allen's first studio album, "Alright, Still" (2006), was released shortly after.
 The album was commercially successful, earning a three times platinum certification in the United Kingdom, and gold in the United States.
 The album was nominated for Best Alternative Music Album at the 50th Grammy Awards.
 Follow-up singles "LDN", "Littlest Things" and "Alfie" did not repeat her early success, although they still sold well; "LDN" peaked at number six on the UK Singles Chart.
"Littlest Things" is a song by British recording artist Lily Allen from her debut studio album, "Alright, Still".
 Written by Allen, Mark Ronson and Santi White, the song was released as the third single of the album on 11 December 2006 by Regal Recordings.
 It incorporates a piano sample from Pierre Bachelet and Herve Roy's music from "Emmanuelle", for which they were credited as co-writers, as the lyrics tackle the singer dealing with the departure of her boyfriend, while reminiscing about their time together.
 The song was created in a New York studio, after Allen had met Ronson, who was impressed by her previous work and offered her different samples.
