this is worse than downloading it for personal reasons. You're trying to steal it and use it for profit. You should buy it. If you were making the music, would you want dj's to do that to you?
Additional:
I don't mean to sound rude. Hopefully its not coming across that way. I work in the music business and have watched it suffer from things like this. When I got into it, it was great. Over the last 12 years its just been destroyed. Records labels are struggling to actually pay for studio time. They still have money, but are having to cut budgets to get the albums done which makes the music suffer.
Where to get it, buy it. Use itunes or walmart.com so you don't have to buy whole albums. You can select each song you want.
You're going to make money djing. If it is a legit business, you'll have startup costs just like everyone else. Factor that in to your budget.
By the way, Serato makes great stuff. I use Pitch and Time in the studio all the time.
