For my ex, I made her a mix of all the mellower stuff ("To Bid You Farewell", "Benighted", "Atonement" and stuff like that. Hell even "Shilouette"). She was never going to get use to the death metal bits, but at least she had an appreciation of how great the band, in her case, could be, lol. A lot of people would probably wonder why they just don't do the mellow stuff all the time, but it is their loss. Personally I'm not too worried what my friends or family think of the music I listen to and to be honest I don't think much of a lot of theirs but we at least have some common ground so we can get along.
