You can achieve it by using the following code.For your requirement,I have stored the column names into array in hard coded manner.If you want to be dynamic, then you can store the column headings into hash.At the time, you can't expect the hash keys to be in order.First, you check this.If you face any problem, I will explain you with storing and retrieving the details from hash.

use strict;
use warnings;

my %hash; #declaring hash for storing the data

open FH, "<input.txt" or die "can't open file:$!"; #opening the file i
+n read mode


my $i=0; #declaring iterator for storing different records in a file

my @arr; #temporary array to store splitted details


while(<FH>) { #reading data from file
    if(/^Artist:\s*(.*)$/) { #checking whether its first artist detail
+s
        $i++; #incrementing the iterator for storing the details
            push @{$hash{$i}}, $1; #pushing the artist name to array
            while(<FH>) { #continue reading the file to get artist det
+ails
                if(/^Artist:\s*(.*)$/) { #checking whether particular 
+artist details completed
                    $i++; #incrementing the iterator for storing the d
+etails
                        push @{$hash{$i}}, $1; #pushing the artist nam
+e to array
                        last; #break the loop
                }
                else {
                    @arr=split(':'); #splitting the field name and val
+ue
                        $arr[1]=~s/\s//g; #removing the unwanted space
+s in file
                        push @{$hash{$i}}, $arr[1]; #storing the furth
+er informations into array
                }
            }
    }
    else {
        @arr=split(':'); #splitting the field name and value
            $arr[1]=~s/\s//g; #removing the unwanted spaces in file
            push @{$hash{$i}}, $arr[1]; #storing the further informati
+ons into array
    }
}

my @fields=('Artist','Title','Album','Year','Genre'); #storing the fie
+ld names in the file in order

print "$_\t" for @fields; #printing the column headings

print "\n-------\t-----\t------\t----\t-----\n"; #printing the ----- a

for my $key (sort keys%hash) { #getting the records in order from hash
my $j=0;
print $hash{$key}->[$j++]."   " while($j<5); #getting all data of arti
+st from hash and printing it
print "\n"; #printing newline for differentiating the records
