Auto selecting the "Purchase music for download" AR when pasting 7digital.com URLs and cleaning them up would be nice.

Artist: http://www.7digital.com/artist/the-impatient-sisters
Release: http://www.7digital.com/artist/el-p/release/cancer-4-cure-1

There are also country/language specific stores whose URLs swap out the "www" for the country code e.g.
Spain: http://es.7digital.com/artist/the-impatient-sisters
French Canadian: http://fr-ca.7digital.com/artist/the-impatient-sisters

One exception to this is the Australian store whose URLs look like: http://www.zdigital.com.au/artist/the-impatient-sisters

These shouldn't be corrected to "www.7digital.com" because much like on iTunes, not all releases are available in all countries e.g. the Singaporean store does not currently have the release used above.
