So long at it seems to be mostly bad puns, let's see if anyone can recognize the bands/songs from the code snippets:

    !( $this->isa( 'exit' ))

    until ($brooklyn) { } continue { sleep() }

    while ($america) { $america->DESTROY }

    `touch evil`

    @ways_to_die == 99

    @fix == 1

    $self->name eq 'mud'

    7 + 7 ==

    die unless $too_tough;

    if ( $you->buy('cd') ) { $self->get('porche') }

    require 'English' || die

    (! $self->believe() )

    $technicolor->blur()

    $self == $hell

And, for the case of no real code involved, but search engines probably won't help you: (okay, with the one word names, there's probably more than one artist who have songs with these titles)

    time

    if

    $pass && $fail

    split

    Test

    use less

    sleep

    push

I guess one hint -- they're in alphabetical order by artist name (as I just browsed through my listings)

Update: well, no one seems to have tried guessing in the ~40hrs it was up, so here are the answers:
