Spotify Song Suggester

This project is part of the LambdaSchool Build week March 2020

Project Objective

The Song Suggester has two functionalities on the DataScience side:

• Given a song chosen by the user the API will return the 6 most similar songs from a database of over 300.000 songs.
• Given a song chosen by the user the API will return the least similar song.

Methods Used

• knn

Python 3.7 Libraries

• Pandas
• Joblib
• flask
• Numpy
• sklearn

Setup

• The trained model is under static
• The train data aswell

Notebook: Knn_and_least_similar_song

• Points 1 - 3 document the steps that were taken to create the training data of the model
• Points 4 -8 demonstrate the training of the knn-model and testing it by using the spotipy-api to generate input.
• Point 9 shows the least similar song search using Numpy.
• Point 10 holds the code to get a 30 second demo of a song via the spotipy api.
• Point 11 contains a short discussion why we chose Knn and did not opt for a neural net.

API

The DS api for this project has 3 endpoints

• https://spotify-suggestor.herokuapp.com/song?title=&artist= (returns information about the song)
• https://spotify-suggestor.herokuapp.com/suggestions?title=&artist= (returns 6 most similar songs, along with data for graphing)
• https://spotify-suggestor.herokuapp.com/least?title=&artist= (returns least similar song)

Url Parameters: title (song title) artist (artist)

Results will be returned as long as one of the parameters is entered, and is a valid artist name/song title

User input is sent to the spotify api in order to retrieve correct song info and audio features
