Hey, nice grid, nice and easy. Could I suggest widening the possibilities for answers (for example, "suits" was not accepted for the cards line and maybe "broadcasters" as well as "channels on the tv")? Later, to make it a little harder for people, try to think of words that could fit in more than one category, like, I don't know, Jefferson Starship could fit the music bands as well as the "star" line. Well, not exactly, but you get the picture. I have never heard of any of those musical groups, but I'm sure they are very good, since you put them there. Have you ever heard of "The Rolling Stones" or "The Doors"? Well done, keep up the good work!

suits not acceptable, tv stations not acceptable. Love it

Just a bit too easy, this one - there are no red herrings and nothing that could fit into more than one group.

Would look a bit more professional if you capitalised the clues, and would play a bit better if you threw in a few overlaps. Still, 10/10 in 10 seconds is a new record for me.

They are called suits, so suits should give correct response.

that to easy freddy arnold I will find you and be beter at maths than you.
