Hi! Alvar Hanso
First I am very very shocked and sad that you want like others to get something without paying for it because as someone else has said it is Illegal.
As for myself I download from HMV and did also from Woolworths although I am also with Tesco from which I can also download.
Not only that but once you have signed up with HMV although I'm not sure about Tesco as their download site has change since I last used it, however with HMV once you have put your payment details in you can not only download but you can also order items through the post such as any special CD's and DVD's etc which you want.
And the cost per track will on both HMV and Tesco be from around 79p if you only want a single track which I find is really good.
Happy Downloading!.
