Title: Feature Request: Gamification System (Badges, Achievements & Milestones)

Description:
Hi team! I love stats.fm, but I think adding a gamification system with badges and achievements would take the app to the next level. It would make exploring our listening habits even more fun and engaging.

Here are some ideas for badges and milestones:

• The Dedicated Fan: "Top 1% listener of an artist for 3 months in a row."

• The Marathoner: "Listened to music for more than 5 consecutive hours."

• Night Owl: "Most of your streams happened between 1:00 AM and 5:00 AM this week."

• Genre Explorer: "Listened to 5 different genres in a single day."

• Time Traveler: "Listened to tracks from 5 different decades (60s, 70s, 80s, etc.) in a week."

How it could work:
Users could showcase their favorite badges on their stats.fm public profile. We could also have a dedicated "Trophy Room" tab to track our progress and compare unlocked achievements with friends.

I think the community would absolutely love this! What do you guys think?
