# 🎵 Music Feature Dataset Analysis

Welcome to the Exploratory Data Analysis (EDA) of a music feature dataset. This project aims to uncover insights into how audio features of songs influence user preferences, using the `liked` column as the target variable.

## 📁 Dataset Overview: `train.csv`

This dataset contains various musical/audio features for tracks, along with a `liked` score representing user preference.

### 🎼 Features Description

| Feature           | Description                                                           |
|-------------------|------------------------------------------------------------------------|
| `danceability`    | Suitability of a track for dancing.                                    |
| `energy`          | Intensity and activity level of the track.                             |
| `key`             | Musical key as an integer (0 to 11).                                   |
| `loudness`        | Overall loudness in decibels (dB).                                     |
| `mode`            | Tonality: major (1) or minor (0).                                      |
| `speechiness`     | Presence of spoken words in the track.                                 |
| `acousticness`    | Likelihood the track is acoustic.                                      |
| `instrumentalness`| Predicts whether a track contains no vocals.                           |
| `liveness`        | Presence of an audience in the recording.                              |
| `valence`         | Positiveness conveyed by the music.                                    |
| `tempo`           | Tempo in beats per minute (BPM).                                       |
| `duration_ms`     | Duration of the track in milliseconds.                                 |
| `time_signature`  | Estimated time signature (usually 3, 4, or 5).                         |
| `liked`           | User preference score (continuous numerical value).                    |

## 📈 Key Findings

- 🔹 Features like `energy`, `valence`, and `danceability` have **positive correlation** with the `liked` score.
- 🔹 Features like `key` and `mode` show **low or no correlation** with user preference.
- 🔹 Most features are approximately **normally distributed**.
- 🔹 Tracks that are **highly energetic, positive, and danceable** are generally more liked.
