the ruby code could be simplified:

file, length, name, title = line.chomp.split(/\s*\|\s*/)
name.squeeze!(" ")
=>
file, length, name, title =line.split /\|/
name.strip!

also, if min and sec are numbers, they should be kept in number 
variables imho. but it makes the code look more complicated to newbyes 
so it's discussable:
mins, secs = length.scan(/\d+/)
songs.append Song.new(title, name, mins.to_i*60+secs.to_i)
=>
mins,secs = length.scan(/\d+/).map {|i| i.to_i}
songs.append Song.new(title, name, mins*60+secs)
