+### 📊 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.
+
+## 6️⃣ Recommended Visual Explorations
