As well as being able to manage many other portable players apart from the iPod, this player integrates dozens of streaming radio stations to listen to anywhere with an Internet connection. It also includes a very good search engine for YouTube videos related with the songs that we are listening to.
Among the formats that are compatible with aTunes, we will find MP3, WMA, OGG, WAV, MP4 and FLAC, so there will be very few audio files that we can't add to its library. As a complement, it allows us to rip our CDs to increase our digital audio library.
Even though it has a rather over elaborate interface, it isn't too hard to find any of the options, because in general it is very similar to iTunes.
To sum up, a really interesting audio library organizer and player that can replace iTunes without any problems.
