If you're looking for lyrics to add as a guest artist, here is a verse that fits the 2015 "diss" style:
Social commentary on the "ayan" subculture (typically associated with specific street fashions and lifestyles in Turkey during that era).
(Intro: Bass kicks in) Mahşer burada, ritim damarda patlarAyan ablalar boş lafla vakit atlarKöşe başında değil, mikrofon başında biz2015 hatırası, kalıcıdır bu iz.
(Verse) Nike ayakkabı, fosforlu ceketler yalanSözlerim mermi gibi, geride kalmaz talanDiss mi istediniz? İşte size gerçek sesMahşer’le beraber aldık her yerden nefes! 3. Collaboration Ideas
Look for creators who specialize in Bass Boosted or Arabesk Rap beats, which were popular for these types of tracks in 2015.
