Finding tag info

Got a clip 3 weeks ago, had a few problems, straightened out now and love the clip:smileyvery-happy:

My son gave me a couple of CD’s that have an assortment of songs from XM Radio’s X Country station. I thought I saw a message somewhere about a web site that will compare your file to song files and tell you what artist, title, ect.

Anybody know this web address?

Thanks in advance
