Anyone know of some Metal/Heavy Metal without (or with very little) Lyrics?

There is a lot of Metal out there where I just like the music itself but I hate the singing/screaming/growling-choking?/ect that they have. There are so few songs that I like that have singing in them. h34r:

Edit: I remember hearing about programs that could remove the vocals from music files or something, anyone have info on that?
