The licenses of both datasets allow for free use for non-commercial research purposes. We also encountered difficulty scraping lyric catalogue websites, such as AZLyrics, MetroLyrics, LyricsFreak, and Genius, due to rate limiting or other anti-scraping solutions. We recognize a bag-of-words model is not ideal for natural language processing however, we preferred to keep our project within the copyright laws of the United States. This constitutes the largest, clean lyrics collection available for research. Out of this collection, MXM provides 237,662 tracks in its MXM dataset. The MXM dataset provides a bag-of-words model covering the 5,000 most popular words across the lyric dataset for over 77% of the MSD tracks. The MSD contains audio features and metadata for a million contemporary popular music tracks, provided by The Echo Nest. DATAįor our song lyric data, we use the musiXmatch (MXM) dataset, a complementary dataset to the Million Song Dataset (MSD) from LabROSA at Columbia University.

We measure the quality of our algorithms with a manual evaluation survey. We rely on a song lyric dataset, song popularity, naïve word frequency analysis, k-nearest neighbors classification, and sentiment analysis to generate matches through two unique algorithms. We hypothesize that by analyzing a body of text and comparing its features to the features of song lyrics, Triqtunes may suggest songs matching the content of sentiment of the submitted text. After installing Triqtunes, a user highlights text in her browser, sends a request to our server for a song, and receives a response with recommendations in the form of Spotify stream URIs, seamlessly playable from within the browser. To solve this problem, we created Triqtunes, a Google Chrome extension built to automate this process. However, the selection of web page and song is often mutually exclusive, and bridging this gap requires periodic intervention from the reader. The name is a play on the Million Song Dataset, which includes metadata and features for 1,000,000 music recordings.Those browsing the Internet often, and increasingly, augment their experience with the accompaniment of music. They were scraped from publicly-available sources on the internet, and then de-duped according to their MD5 checksum.Ī lakh is a unit of measure used in the Indian number system which signifies 100,000 (or, in the Indian convention, 1,00,000).ĭepending on how you count, the Lakh MIDI Dataset includes about 100,000 MIDI files.

The remaining entries were compared using standard (and computationally expensive) dynamic time warping-based MIDI-to-audio alignment.įor a thorough discussion, please see chapters 4-7 of my thesis.Īnd, of course, all of the code used in this project is available here.

In short, I developed series of efficient learning-based methods to discard the vast majority of possible matches the Million Song Dataset.

How were the matched and aligned datasets assembled? However, the DTW-based alignment scheme is intentionally somewhat invariant to differences in instrumentation.Īs a result, songs which are harmonically similar may be matched incorrectly.Īs a concrete example, it's not uncommon for transcriptions of house music to be erroneously matched to dozens of house remixes.

This tutorial addresses these questions in detail.Ī MIDI-audio pair was considered a valid match based on the confidence score reported by dynamic time warping-based alignment, which turns out to be extremely reliable.įor more discussion and concrete details, see section 4.5 of my thesis. This gets at two questions: How reliable are the annotations in MIDI files, and how accurately was the MIDI file aligned to the audio recording? How reliable are MIDI-derived annotations? In some cases, MIDI files include key signature annotations and lyrics, among other useful things.įor a discussion of the presence of these different information sources in files in the Lakh MIDI Dataset, see this tutorial. In a simplistic view, a MIDI file can be considered a score with additional optional annotations.Īs a result, you can count on getting a transcription of the song, as well as meter information such as beats and downbeats.

How to utilize the Lakh MIDI Dataset, with examples.To facilitate use of this dataset, here are a few IPython notebook tutorials: In Proceedings of the 12th International Society for Music Information Retrieval Conference, pages 591–596, 2011.
