I listen to a lot of DJ mixes and often find an awesome remix, Shazam it and come up with nothing (not the right remix) from the Apple iTunes store. Luckily enough – just when you thought you were out of luck – you have another option: Beatport I generally keep up with their Top Ten as well – and find that I am about 1-2 weeks ahead of the radio stations on what is the “it songs”. (Example: Summertime Sadness – well before the radio started playing it non-stop).
So – next time you are looking for a remix you cannot find on the Apple iTunes store – make sure you check out Beatport.
