IPhone is a very aggressive beat. It has this outstanding flute that is playing constantly and with no break.
Special about tis one is on one hand the flute like we said before, but on the other hand it is this clock sound at the beginning. This sound you hear a lot in FruityBeatz productions.
The beat iPhone is made for rap and has, besides the flute, not much melody in it. So you can definitely try to sing to it, but it could get difficult. So to be on the safe site, just throw a hot verse on there.
After all this is a well produced beat, that has everything in it to be a big record. The drums are banging and the flute melody is so catchy. A round one.
