There are thousands of threads about this on the internet, as a dj surely you should have some sort of prior knowledge or ideas of what you like…
Your best bet is too go out onto the internet and find a few controllers and ask about them to see what people think, also the kind of music you play would help, your price limit and what platform you are going to be running it on (windows or mac). if you want to use digital vinyl/cd or complete controller based setup.
if you have any other software already (you said musician so do you have ableton?)
Digital dj’ing is such a big realm that its hard to just say “I think you should get this…”
most software comes with Itunes intergration or at least click and drag from Itunes into a deck.
as far as easy simple controls, nearly all programs out there let you map software-controllers how you want so in fact you can have a loop button that actually works as a play button or a bass knob thats a volume knob etc….
its all about how you work as a person and what youd like. check out http://www.htfr.com and see what controllers interest you.
