Affiliate Marketing Secrets

I am preparing to launch a CD into a niche market, and would like to make tracks available for sale through my website. I would like visitors to be able to select a track to purchase, hear a sample, then proceed to a page to purchase the full track, being provided with a link to download the track after payment. Most importantly, I would like the link to expire within 24 hours and only allow one download so that the link is not shared or used to gain access to other tracks on the server without paying…how do I do this???

I’m thinking of starting an online biz which focuses on two main themes – music and history.
Do u think this is considered a niche biz idea? How marketable or profitable and well-received would this idea alone be?

All it does is create karaoke singers who just become clones of whatever the market needs. They have a shelf life of a few years before they are fazed out and replaced with a new X-Factor star.
The live shows guest stars are predominately previous contestants or affiliated to Simon Cowell some other way.
It’s just music for fans of the Music Industry rather than fans of Music itself.

I think the ipad reaches a certain niche (apple fanboys). For individuals that actually possess a penchant for reading, they like e-ink tablets. All the multimedia distractions such as music, game and apps aren’t necessary. There is also that large niche that loves to read news articles and publications online. It would be nice if the kindle had a better web browser that was fast and efficient so reading the NY Times, WSJ, etc. would be more copacetic. I wouldn’t mind a sacrifice in battery life for better performance as long as there are no distractions.

Ohhkaii so this is my first question ^^
And its quite confusing .
Its just I dont know who I am . I feel so abandonned . As if no one wants me in their life . Everybodys forcing me to do things I dont like . My favorite / talent is art & music (piano or vocals) but my parents dont appreciate it . They want me to be good at the academics , something I really really try to do good at , but its just … I dont know how to explain … not something my HEART wants .
If I told my parents I want to be a model , theyd be screaming at me and ground me for years and not talk to me .
And my school life . My friends , for example . I never feel like fitting in . Dont get me wrong . I have a lot of friends . But not one best friend that I can actually trust and share my feeling with . And guys . I attract the wrong type of guys . Jocks that only want a one night stand or seeing if I can fck them hard . I want a nice boy that I can relate to . Likes my type of music (rock , screamo , bands) & knows how I feel .
Whats wrong with me ? Have I just not discovered my niche in this world yet ?
Also a little more information : I have a councellor / therapist .
And next month Im going to check if I have any sort of depression or short attention span (what was it called again ? A_ _ )
And my life is exactly the same as the song “Welcome to My Life” by Simple Plan .
But help me please ? [:
Thank you ! <3
