What are some good screamo party songs?

2. Still Fly - The Devil Wears Prada
3. Chelsea Smile - Bring Me the Horizon
4. Swing - Miss May I
5. Downfall of Us All - A Day to Remember
6. You Give Love A Bad Name - Atreyu
7. What This Means to Me - I See Stars
8. Hot Grill, and High Tops/ Stick Stickly - Attack Attack!
9. Pokerface - Of Mice and Men
10. Six - All That Remains
11. Ambrosia - Alesana
12. Sex Ed Rocks or Crank that Calvary Boy
13. Me and Zoloft Get Along Fine - Dance Gavin Dance
14. I’m Not A Thief, I’m A Treasure Hunter - A Skylit Drive
15. Back Burner - August Burns Red
16. Romance is Dead - Parkway Drive
17. The Sound of Truth - As I Lay Dying
18. The Journey Down South (Starts With A Two Step) - Before Their Eyes

Hope this helps!
