your problem is that you create an empty array above, then below you
iterate same empty array and push nothing into it!

> songs.each {|song| songs << Song.new(song.name, song.owner)}

this should get you going in the right direction, assuming your cvs
list is comma separated


# create a test cvs list
#
cvslist = []
cvslist << "song1,owner1" << "song2,owner2" << "song3,owner3"

# get song and owner strings
#
cvslist.each do |item|
song,owner = item.split /\s*,\s*/
  puts song
  puts owner
end
