Step 1 - Signup to a cpa network with direct linking
Step 2 - Find a list of current top 10 pop songs
Step 3 - Create a video for each track and upload to youtube with the title: [track name] + lyrics
The video can be the full track but if you dont want to go against copywrite laws, then you could just use a video of a picture of the artist without any audio
In the description, insert something like: "download the full album for free", or if you used a blank video: "youtube made me delete this video but you can watch/listen/download it here"
After that, you insert a direct link to a cpa offer (use a url shortener first)
Its as simple as that
People will follow the link and hopefully complete the offer. The convertion rate for this is quite low as you can expect but hey, money is money right?
