          "OK Computer is the third studio album by the English alternative rock band Radiohead, released on 16 June 1997 on Parlophone in the United Kingdom and 1 July 1997 by Capitol Records in the United States. It marks a deliberate attempt by the band to move away from the introspective guitar-oriented sound of their previous album The Bends. Its layered sound and wide range of influences set it apart from many of the Britpop and alternative rock bands popular at the time and laid the groundwork for Radiohead's later, more experimental work.",

          'Dummy is the debut album of the Bristol-based group Portishead. Released in August 22, 1994 on Go! Discs, the album earned critical acclaim, winning the 1995 Mercury Music Prize. It is often credited with popularizing the trip-hop genre and is frequently cited in lists of the best albums of the 1990s. Although it achieved modest chart success overseas, it peaked at #2 on the UK Album Chart and saw two of its three singles reach #13. The album was certified gold in 1997 and has sold two million copies in Europe.

// Practicing with find
// Let's start by focusing on just one artist: Radiohead. 
// Find the album called "King of Limbs."
// 1. Get the list of Radiohead Albums. You can access musicData[0] for this
const radioheadAlbums = musicData[0].albums
// 2. Find by the album's name.
const matchingAlbum = radioheadAlbums.find(album => album.title === 'King of Limbs')

// Practicing with filter
// Get every song on the King of Limbs with a title longer than one word.
// Note: You can turn the title into an array of its words using the .split() function! Look it up to see how it works.
// 1. Get the list of King of Limbs songs. You can use your result from the previous question for this.
const kingOfLimbsSongs = []
// 2. Find the list of matching songs
const longerSongNames = kingOfLimbsSongs.filter /* your code here */
                                           
// Practicing with map
// Let's figure out how may seconds long each song is.
// To make this easier, let's just focus on songs for Portishead's Dummy.
// 1. Get the list of songs from the album. You use array indices to access this.
let dummySongs = []
// 2. Map to the song's length in seconds, using basic multiplication. (remember! These functions don't mutate the actual array. You have to reassign, to a "songsInSeconds" variable in this case.)
const songsInSeconds = dummySongs.map /* your code here */

// Practicing with reduce
// Now, let's see how long OK Computer is.
// 1. Get the list of songs for OK Computer.
const okComputerSongs = []
// 2. Calculate the length of the album using reduce!
const albumLength = okComputerSongs.reduce /* your code here */

// Getting fancier

// Get every third song on the "Third" album.
// Note: There are more parameters to the filter callback function than just the current item in the list!
const everyThirdSong = []

// Find the albums with descriptions longer than 90 words.
// Note: You'll have to loop over the list of albums for both artists! You can use a loop for this, or the fancy forEach() function.
const longerThan90 = []

// Get the list of songs across all albums
// Note: This requires some nested looping. I would also recommend something that rhymes with "shmaccumulator" for the outermost callback!
