YouTube has a vast and truly amazing catalogue of music and we're working intently on our algorithms and interfaces to bring that music to listeners in a unique way. Presto.fm definitely does have aspects that are similar to the Pandora-style of music service, although our catalogue of music is quite a bit larger and we do have some unique features all our own (and some that are more similar to Spotify & Songza). Thanks again for you feedback, and happy listening! p.s. The great thing about YouTube is that anyone can publish content, but it does mean that occasionally the wrong video sneaks into a playlist. Sometimes it's a serendipitous discovery of a new artist covering an old favourite...and sometimes it isn't. We aim to make it a very rare occurence for Presto to interrupt your playlist with an incorrectly labelled track and Presto has quite a few filters in place to exclude them. We're always fine-tuning the algorithms to improve them, so let us know how we go!
Also, under your 'About' tab hidden at the bottom you have a typo: >We're Australian based so that usually means even when international music services let us listen they don't have they local or niche artists that we want to hear. Again, you guys did a great job so far.
