Generating Band Names and Song Titles
Yesterday my distinguished colleague Stuart Langridge said he could use some fake band names for functional tests in the Ubuntu One Music Store he's working on. Since I'd done a similar thing once before (for realistic sounding Dutch city/village names.) I figured I could hash an algorhithm out pretty quickly, and so I did, last night.
I started with a simple Markov chain class that can analyse a body of data and then generate text that is like the source data, but does not actually occur in it. At first I used the same algorithm for artist names and song titles, but I soon decided generating songs word by word, and artist names character by character made more sense, since proper names (and a lot of band names) don't adhere to spelling rules anyway.
The song titles came out pretty great (as in, in every batch I generated there were at least a few funny ones,) but the artist names remained problematic, so the next thing I tried was splitting the artists into groups and people. This seems to be generating even better results, but splitting the list of artists (which I generated with a throwaway plugin for quodlibet, see below) turns out to be a lot of work. I did a few hundred manually, and the results below are quite cool, but there's a lot of partial duplication. Perhaps I shall finally download the musicbrainz data set, and see if I can generate separate lists of people and groups/bands from that easily. (HINT: if someone has such lists lying about, I would be immensely grateful if you could mail them to thisfred at gmail. That would be me.)
Anyway, here's a single unedited run of the script:

As you can see there's a lot of names that are too close to real names to be interesting, and quite a few common patterns. Also broken parentheses, due to (my implementation of) Markov chains being only mildly context sensitive. (See how I used that term in an actual sentence? Totally worth it, that education.) Also, I can't guarantee that none of these titles or artist names aren't actually real, because of trivial lower case/upper case and or white space and punctuation differences, or, due to the artist not being in my source data set.
And here's the code that generated it:
import random
class Markov(object):
def __init__(self, words=False):
self.db = {}
self.lines = set([''])
self.words = words
if words:
self.prevs = 2
else:
self.prevs = 3
def process_file(self, filename):
with open(filename, 'r') as file:
for line in file:
self.process_line(line)
def process_line(self, line):
self.lines.add(line.strip())
prevs = []
for i in range(self.prevs):
prevs.append(None)
if self.words:
line = line.split()
line.append('\n')
for character in line:
self.db.setdefault(
tuple(prevs), []).append(character)
prevs.append(character)
prevs = prevs[1:]
def generate_line(self):
line = ''
tries = 0
while line.strip() in self.lines and tries < 100:
tries += 1
prevs = []
for i in range(self.prevs):
prevs.append(None)
line = ''
while True:
char = random.choice(self.db[tuple(prevs)])
if char == '\n':
break
prevs.append(char)
prevs = prevs[1:]
line += char
if self.words:
line += ' '
return line.strip()
n = Markov()
n.process_file('names.txt')
g = Markov()
g.process_file('groups.txt')
t = Markov(words=True)
t.process_file('titles.txt')
for i in range(100):
x = random.choice([n, g])
print x.generate_line() + ' - ' + t.generate_line()
[Edit]: removed a redundancy left by earlier refactoring.
And here's the dead simple quodlibet plugin, just to show how cool quodlibet is. Note that quodlibet, unlike for instance the also quite nice Rhythmbox, would allow you to do this (or much more interesting things) with *any* id3 tag, including ones you make up yourself.:
import os
import const
from plugins.songsmenu import SongsMenuPlugin
class AddToListPlugin(SongsMenuPlugin):
PLUGIN_ID = "Export artist list"
PLUGIN_NAME = _("Export artist list")
PLUGIN_DESC = _("Add artist name to artists.txt.")
PLUGIN_ICON = "gtk-find-and-replace"
PLUGIN_VERSION = "0.1"
def player_get_userdir(self):
"""get the application user directory to store files"""
try:
return const.USERDIR
except AttributeError:
return const.DIR
def plugin_songs(self, songs):
f = open(os.path.join(self.player_get_userdir(), "artists.txt"), 'a')
artists = set()
for song in songs:
artist = song("artist")
if artist in artists:
continue
artists.add(artist)
f.write('%s\n' % artist)
