Use the cat, awk, sort and uniq $-$c command to get the title of all the albums $($along with the artist name$)$ with a count of the number of tracks in it$.$ The album title is in the $2$nd column and the artist's name is in the $1$st column of the csv file. Then we can pipe the output to sort $-$rn and sed command to get the top five albums by the number of tracks.
