Thank you, everyone, for sharing your answers!
MCSkwAyrD93, Thank you for reading my hub! I like the artists you listed.
I think that because we don't listen to entire albums anymore, artists are now less concerned with making a complete album or concept album because people will just choose the songs they like and disregard the others.
Examples of amazing albums I love to listen to all the way through are Pink Floyd's Dark Side of the Moon and U2's Joshua Tree. They both have hit songs on them, but as complete albums, they are amazing.
