No.

Creates attr reader methods but does nothing about values.

Initializes values but does not create reader methods.

You can make your life easier by using Struct:

Song = Struct.new(:name, :artist)
s1 = Song.new "foo", "bar"

Struct will create setters, getters and an appropriate constructor
(#initialize)
