I'm having trouble giving AudioHero any sort of trouble over the slightly clunky UI and the slightly annoying playlist issues because everything else is such a great use of your time and money that it's more than easy to look past it. You get detailed invoices for your own recordkeeping each time you download a set of sounds or tracks, and you can even pull the STEMS - something I feel gets overlooked in the reviews, because this allows for so much more control and flexibility with complex projects. For larger teams, it may be a nuisance to buy multiple licenses, since this only covers one user - but for the individual, it's invaluable as a tool. The quality of the sounds and tracks are great and some are especially memorable. Absolute gem of a deal (they were also on Humble Bundle but only a small predetermined percent of their library was offered, not the entire growing catalog).
