After IOS 5 upgrade my songs are grayed out

[gunzrool]

Hi i need help!
After upgrading to ios 5 most of my songs are grayed out and dose not get updated.
I tried various solutions provided and discussed in many forums but none worked for me. Issue currently is that i have nearly 1300 songs on my iphone 4, when i connect to itunes i cannot see the list of songs but itunes shows the space consumed bu these songs.
I need help in deleting these songs of my iphone4 so that i can load them again and start listening to music.
Please help me!

Sam
