However I personally like all the below players
Poweramp -
link
Many claim it to be the best player - one awesome thing is that you can change the bass in it...its really good
Winamp- link
This one is real good too.. I like this the best...
Player Pro -
link over all very good...gives you an option to use your volume keys to previous or forward the track while the screen is locked
Ubermusic link If you use zune and you like it , this will be really your jack pot...very much like the windows player..
Doubletwist link Really good for wireless syncing...if you are a lazy one who transfers whole playlists thru wi-fi then go for this, however you will need to install it in your system too and should have
airsync app too
Neutron MP link Trust me mate, this is the best music app ever...the clarity and the quality is impeccable in this one..i have no idea how the developers did this so well..right now am not able to afford this app, but the next time my hands get on some cash, this will be the first one i go for...
N7 Player link If you like eye candy for your app, then this one will rock your world...the whole player will give your music data base a cover cloud look which when pinched will go to individual artists..i liked the enqeuing option
Tune Wiki link if you have good net speeds in your place, then this one is an interesting player to use...the moment you play your music, it will fetch the lyrics and play it like karaoke..
P.s ; even the stock player does the job, but once you cross 1500 songs in the database, your stock player will be badly responding, so that is why this app...
Except neuton mp, I have all these apps in ma razr and each of them have their own advs and disadvs...however winamp won my heart as it plays flac well and beats all the ones in equalizer !
