I used to use Mixzing, but I found that the navigation of it wasn't so easy (or intuitive) for instance playing all albums from one artist, the weird way it imports/organizes play lists and the not-so-easy way to navigate back from "now playing" to the "artists" section.
I was looking pretty hard for the best music player on the droid and Btunes has now done it in my opinion. The Dev is crazy, I bugged him about fixing some **** and he did it in less than a day. Btunes downloads album artwork just like Mixzing as well, so I don't see how Mixzing is better in that respect. Btunes is also really new...but still the most functional IMO! (This is not spam, just a satisfied custy).
I like the gui for btunes, but there has been so many times that I add music to my phone and it doesn't pick it up -even after manual scans, the stock player does. I uninstalled it and am just using stock now.
jsut tried it,my SD card is very organized by artist adn cd but it still managed to only pick up a few songs per cd, uninstalled, im sticking with 2.1 stock and pure music widget.
To the OP, im smelling spam.
If your just trying to share your findings that is fine....but as someone else said the people developing btunes have been promoting it in a very spam like way. I liked the ipod touch feel to it but i didnt like the fact that it didnt recognize most of my music...and i use albumartwork to get missing album artwork so no big deal there. the 2.1 music app is better than the stock one and with a nice widget like the pure one, its working well. If btunes fixes the problem of not showing all the music it wont be so bad. Thanks for sharing your findings if thats all you were doing.
