What is it?
It's an application similar with the Music.app on your iPhone/iPod Touch. Besides the normal music playback capability it has some interesting extras. It is available for free using the Cydia installer.
– easy to use navigation buttons
– album art support for your music collection
– live song lyrics – sing along with your favorite tunes, and contribute back to the project with lyrics for your songs if they are not in the database.
– music maps – see what songs are playing near your location or in a specific region (like the United Kingdom)
– Tune Wiki Top 50 – see what other Tune Wiki users are playing
– help menu – shows you how to use the tunewiki interface
– very good reliability – never crashed during my tests
– it needs an internet connection, either WiFi or EDGE/3G because all the information displayed is stored on Tune Wiki's servers.
– can be sluggish in low performance network conditions
TuneWiki is a great replacement for the standard music.app, provides great functionality and is a pretty good reason to jailbreak your iPhone/iPod touch – if you haven't done so already.
