This repository contains a comprehensive exploratory data analysis (EDA) on a music features dataset. The primary objective is to understand the patterns in audio features and analyze how they relate to user preferences, providing insights for music recommendation systems and user profiling.


## 📥 Dataset Overview

The dataset (`data.csv`) contains audio features extracted from music tracks along with user preference scores. This rich collection of acoustic and musical attributes enables deep analysis of what makes music appealing to listeners.

**Total songs:** 195

**Format:** CSV (data.csv)

**Source:** Spotify API

**Target column:** liked (1 = liked, 0 = disliked)

**Data type:** Tabular

**Licensing:** For academic and personal research use (derived from Spotify API)



## 🎼 Features Description

| Feature | Description | Data Type | Range/Values |
|---------|-------------|-----------|--------------|
| `danceability` | Measures how suitable a track is for dancing based on rhythm, tempo, and beat strength | Float | 0.0 - 1.0 |
| `energy` | Intensity and activity level representing loudness, dynamic range, and general entropy | Float | 0.0 - 1.0 |
| `key` | Musical key using standard Pitch Class notation | Integer | 0 - 11 |
| `loudness` | Overall loudness measured in decibels (dB) | Float | Typically -60 to 0 |
| `mode` | Modality of the track (Major = 1, Minor = 0) | Integer | 0, 1 |
| `speechiness` | Presence of spoken words in a track | Float | 0.0 - 1.0 |
| `acousticness` | Confidence measure of whether the track is acoustic | Float | 0.0 - 1.0 |
| `instrumentalness` | Predicts whether a track contains no vocals | Float | 0.0 - 1.0 |
| `liveness` | Detects the presence of an audience in the recording | Float | 0.0 - 1.0 |
| `valence` | Musical positiveness conveyed by a track | Float | 0.0 - 1.0 |
| `tempo` | Overall estimated tempo in beats per minute (BPM) | Float | Usually 50-200+ |
| `duration_ms` | Track duration in milliseconds | Integer | Positive integers |
| `time_signature` | Estimated overall time signature | Integer | 3, 4, 5, 7 |
| `liked` | **Target Variable:** User preference score | Float | Continuous values |



### 📊 EDA Overview: Music Preference Dataset

## 1️⃣ Null Values Check
✔ The dataset is complete — no missing entries detected.

## 2️⃣ Target Class Breakdown

Liked Tracks (1): 100 entries

Disliked Tracks (0): 95 entries

### Total_Liked_and_Disliked_Songs

![Total_Liked_and_Disliked_Songs](Total_Liked_and_Disliked_Songs.png)

## 🟢 The class distribution is fairly even — no need for balancing.

## 3️⃣ Feature Types

All input variables are numeric.

The target label liked is a binary flag (0 = dislike, 1 = like).

## 4️⃣ Key Statistical Insights

Higher average values for energy, danceability, and valence are seen in liked songs.

In contrast, acousticness and instrumentalness are more prominent in disliked tracks.

## 5️⃣ Correlation Patterns

🔗 Positive: energy strongly correlates with loudness.

🔻 Negative: acousticness shows inverse correlation with energy and valence.

## 🔍 Key Findings

### 🎯 **Primary Insights**

1. **Feature Distributions**
   - Most audio features follow approximately normal distributions
   - `valence` and `danceability` show interesting bimodal patterns
   - `tempo` exhibits a wide range with multiple peaks

2. **Correlation Patterns**
   - **Strong positive correlation** between `energy`, `valence`, and user preference (`liked`)
   - **Moderate correlation** between `danceability` and `liked` scores
   - **Weak correlation** for categorical features like `key` and `mode`

3. **User Preference Drivers**
   - Higher `danceability` → Higher user preference
   - Higher `valence` (positivity) → Better ratings
   - Optimal `energy` levels correlate with user satisfaction
   - `acousticness` shows inverse relationship with preferences


## 📊 Results

### Model Performance Insights
