Thanks for the comments guys!
<To Inanes comment> <oganalp> you beat me to it!
Most price per minute along with other factors such as time frame for delivery, live instrumentation required, quantity and variation of tracks etc. they are only guide as all rates are ultimatley negotiable.
as for underlying noise in some of the tracks I think what you are hearing is more the air between the instruments for example the guitar tracks use drums that have a lot of ambient room sound while some may consider this to be noise just as many would not
<To Bauers Comment>I get asked this quite a lot about the pricing. my justification for this is that when composing 30 seconds of music to specification it can be more complex than creating say a peice of music that lasts 60 seconds or even 180 seconds as the music has a less time to develop so there are more restrictions as to what can be done in terms of getting to the point quickly.
Looking at the page now the rates do seem a little random being not in price order, will be fixed
It was my way of making it value for money in the long run for the client. for example if someone purchased a 30 second track and wished to re-use it for whatever purpose within for example a game, it could become rather repetitive whereas if 60 seconds was requested and purchased then being that you could quite easily have several changes in mood in 60 seconds then you would be able to slice the track and re-use/rearrange it without over repetition
I probably should add that to the site somewhere
I priced it by how much i would like to be charged whilst understanding that I still needed to make money, whilst not leaving the clients wallet dry.
As for hoping somebody bites I wouldn’t mind it at all
