Not mentioned in marketing blurb is a limit on downloads which they arbitrarily imposed. Very slow conversion rate (which takes forever) and clunky GUI which limits options on bit rate conversions - i have a high end sound system and wanted to take advantage of amazon's HD but all these versions are excluded from their conversion subset. The meta formatting of the titles of the converted songs are not original and i have had to edit both the order and the correct names so as to follow established formats for JRiver etc databases. Finally, forget about expecting any customer support as i did not get any responses from my multiple emails. They continued to auto charge despite me cancelling both my amazon and sidify subs. The billing company appears to come from a random east asian company which is totally sus. AVOID!
