From a baseline perspective, while there's a plethora of stuff sampled here, I wasn't 100% happy with the hip-hop stuff on offer (which is why it's awesome you can add your own samples). In fact, as a whole, it all comes across a bit more synth than I'm too happy with, but I can't really complain too much. As mentioned you can manage your own sounds, and really, this is an on-the-go accessible music creation program pretty much anyone can use (I just wanted more 80s/90s beats and samples templated to play with). But that's also an alluring challenge - the toolset here allows you to ultimately generate almost anything you think is missing, which illustrates the overall pint of the program.
So if you're a music lover, or someone who's keen to dabble in the field but are too afraid of the apparent depth of everything else available, Rockstar and Timbaland truly do have what ails you, and I can't stress enough how satisfying it is to seriously just jump into this and try it yourself; all the writing above and hands-off demos in the world won't give you as clear a picture of this programs accessibility as picking it up for yourself, which we wholeheartedly recommend you do.
