Summary of advertisement research

What conventions have I found/ ideas can I draw from existing album release adverts:

• Use the same picture on advert as used on the album cover in some way
• Use the same font style and colour on the advert as digipak
• Should say 'Out Now' or feature a release date
• Can feature a list of hit singles that the album features
• Have logos/symbols of retailers on the bottom such as HMV, iTunes, record label
• Have a website/ facebook and twitter links so the audience can build a more personal relationship with the artist.
