iTunes Keeps Asking Me to Enter My Password Every 15 Minutes

Recently I had to reset all my passwords because I forgot it -- that was little to no problem. But since, iTunes (which I never use, btw) keeps asking me to resign in every friggin' 15 minutes. I mean, it signs me in with no problems. But it seems to sign me out after 15 minutes, and asking me to sign back in. Its really annoying. I cannot see how I could set it to stop doing this; keep me signed in at least. Any suggestions or how-to???

Thanks!
