Your first snippet is close, but thingy is a an array/list, not a hash/dictionary, so you need to index the very first item in that array/list, which is a hash/dictionary: 
name = thingy[0]['albums'][0]['title']

my $name = $thingy->[0]{albums}[0]{title};

For your second snippet, you will need to loop through each hash/dictionary that is contained inside the 'album' array/list: 
for a in thingy[0]['albums'] : a['year'] = 1999

$_->{year} = 1999 for @{$thingy->[0]->{albums}};

As you can see, you don't need a counter, you only need to process each element at a time. Perl and Python are both good about giving the coder 'ease of iteration'. ;)
