Interesting
I can see what you mean about it applying to music; I've noticed that I associate some pieces of music with a particular colour and I've never been able to explain why. And I'm sure I've asked one of my friends to taste whatever I've been cooking and said, "What does that need? It's quite good, it just needs to be more...um...red..."

sounds like you have it, too
I don't think it's all that uncommon - mostly artists and musicians seem to have it

From what you said about the deodorants above
I think you may be right. Having tried vast numbers of beers at various festivals I've usually run out of analogies to 'foody' flavours and starting describing them in terms of "being like that one you had earlier, but brighter."

I'd be interested to test a couple of the songs I get very strong colours from and see if other people get the same colour.

Give me examples!

I may have to give you some esoteric examples
As I don't get a strong colour off all songs. However, I have just been testing the following:
Hooverphonic - Eden, I get a strange, empty plateau, a bit like standing on the surface of the moon, except the rock is a sort of purpley-grey.
Emily Loizeau - Sur La Route, I get a very cold white, like being in a blizzard
The Who - Bargain, mostly black, but like being in a cave where you get occasional flashes of the brown, earthy rock around you.

Everyone seems to have different
a friend of mine has similar things to me with numbers and colours, but our colours don't match at all

I have exactly that!
Songs are colours to me.

For instance, Smells like teen spirit would be purple, whilst the Foo's Learn to fly would be a greenish/teal and the macarena would be orange.

mine is more like
individual notes and sounds having colour or form.

Clearly way more intense!
EDIT: Actually, now you mention it, if I'm playing a synth and fucking about with the noises, the texture of the sound would affect the colour I hear. Individual notes don't have the same effect.

very difficult to describe, though
I have it with ideas, too, which means I can work through concepts in my head that way (sometimes knowing the end product of an argument because the colours and shape fit) but then have to work backwards to put it into actual language

Ok, in that case, you're just a good old fasioned mental.

YAY!

It's reasonably common I think:
hence Blue Note records.
