article: Last month some of the biggest names in music joined Jay Z for the launch of his premium music streaming service Tidal. But despite all the pomp and circumstance, the app is now floundering at the lower ends of the iOS app store chart. At the time of writing the $9.95-a-month (£9.99) service ranked at 872 on the overall download chart and 51 in the music category in the US. Scroll down for video . Tidal's $19.99-a-month app (pictured) launched in New York on 30 March. Following the launch the app jumped to 4th place on the iOS music chart but now ranks at 51 in the music category and 872 overall . While in the UK the situation is worse, with the app ranking at 92 in the music app category, and disappearing from the overall app list entirely. By comparison, Pandora radio and Spotify occupy first and second spots respectively when the iOS and Google Play downloads are combined. For iOS only, Pandora is top, Apple's Garageband is second and Spotify is third. The fall in favour was first spotted by BGR's Tero Kuittinen and the figures come from App Annie and its Intelligence platform. It is not known why the app has dropped so significantly but the price may be considered too high for some users. Many users who downloaded it and are using it during the trial period may be looking to cancel their subscriptions and uninstall, or alternatively coverage of the app has dropped. The membership-based service - similar to Spotify - offers music and exclusive video content that users can stream on computers, tablets and smartphones or listen to offline. Tidal currently has more than 25 million songs and 75,000 music videos in its library. Tidal is billed as the first artist-owned platform for music and video and the service aims to compete directly with Spotify and Apple's music service, headed by Dr Dre. Users can pay either $9.95 a month for a standard streaming service or $19.99 for high quality streaming in the US. The same tiers cost £9.99 and £19.99 in the UK. Unlike rival Spotify, the service doesn't have a free tier - meaning the musicians stand to make more money from it, but this also means it doesn't play adverts. Tidal streams at 1,411 kilobytes per second - above the 320 for subscribers of Spotify. During the launch event on 30 March, Rihanna, Madonna, Beyonce, Usher, Daft Punk, Arcade Fire, Jack White and Kanye West joined a host of other stars as they were revealed as co-owners of the subscription service, created by Jay Z.

Streaming - which allows users to play unlimited on-demand music online - has narrowly edged out CD sales in revenues over the last year in the US. Industry leader Spotify said it has 60 million users with 15 million of paying for the Premium service. Spotify already has a range of rivals including US-based Rhapsody and Google Play. Paris-based Deezer is the second largest service with 6 million customers. It is strong in Europe and last year entered the US as a high-end-only service. Following the launch of Tidal, Spotify's ranking jumped from 20th overall (red) to 16th in the US, and on 5 April it went from third on the music app chart to second place before falling again the next day. In the UK it held its number one position on the music chart and rose from 8th place to 7th overall (blue) Tidal has more than 25 million songs and 75,000 music videos in its library (pictured).

Tidal is said to stream at 1,411 kilobytes per second, above the 320 for premium subscribers of Spotify . Like Tidal, Deezer's elite service uses FLAC files which are larger than MP3s. Apple - which pioneered digital music through iTunes in 2001 - is reportedly also looking to launch a new streaming service as the market shifts away from permanent downloads. Apple earlier made a bid for streaming customers by buying Beats Electronics, run by Dr. Dre. Along with the US, Tidal is available in Britain and France and plans to launch later this year in Australia and Germany.
