Yippee, LTS! You've read Good Omens.
Karen jonasen - if my boyfriend put in a tape while I was singing, I'd dump him on the side of the road. Talk about rude! If he doens't like it, asking you please not to politely might be acceptable, but putting on a tape is like putting on the jukebox at a live music session. (seen that done...)
My current boyfriend and I don't share much in the way of musical tastes - he likes modern alternative stuff, Radiohead, Divine Comedy, and lots of bands I haven't heard of, and my taste is very... varied... but I can listen to his and not mine, and he at least doesn't complain about mine. Our opinions meet in the classical zone, fortunately.
Better than my ex, who liked lots of trance / hardcore dance music, and lots of the recent pop stuff that all sounds the same. (not the distinction - it doesn't all sound the same, just some of it.) I could tolerate a little bit, but...
