Why can't I put songs onto my iPhone?

Anytime I try to put songs onto my iPhone, iTunes always downloads a bunch of apps I don't want or it will put the songs onto my phone but I can't play them. Does anyone know how to fix this?

It might have helped if you described the steps you took to put songs on the iPhone because the obvious possibility is that you made a mistake in how you tried. If I guessed it I'd say you tried by syncing - just about everybody who post iPod or iPhone questions here thinks that you need to sync. Try choosing manual management of music and video and just dragging the music files to the iTunes tab.
