Applications for recognition of music files is especially dear to those who hold a smartphone, and certainly the most popular of these is the Shazam and SoundHound, but those devices using Android, it is advisable to take a look at the application musiXmatch.
The musiXmatch recently upgraded with a new look for the Android 4.0 ICS and includes new music player, and lets you identify songs (tag) without any numerical limitation. More interesting, however, is that it displays the lyrics and about 6 million songs in 20 different languages (Ellinika however we found).
Even when you install it automatically syncs the songs you have on your past, find lyrics, lyrics provide other songs from the same group, and a short biography of the artist or band that you can see and offline.
Finally, when you choose to identify a song, if included in the application database, then displays the lyrics a little audio preview and the option to buy! Of course, not missing the opportunity of sharing information in many different ways (social networks, sms, email etc.).
