I'd love an Android app that is just the main WinAmp window in portrait mode on my phone, and has the same basic features (simple MP3 player basically, maybe try add support for podcasts and some streaming music). It'd be so perfect for my car. WinAmp for car audio, Google Maps for mapping. I know it's purely for the nostalgia kick and the stock audio players work fine, but... WinAmp!
If someone made a music player app that could use existing Winamp skins that would be really cool. If nothing else you've get a lot of nostalgia installs. Also, do sites like Spotify and Pandora have APIs that allow other apps to integrate with their service? If you could integrate the Winamp playlist with different streaming services you would have a cool and useful music player. I don't even buy apps, but I would probably pay a couple bucks for something like that.
Also it needs the equalizer presets. "Rock" was my favorite.
You could look at the task on windows and see it grow slowly over time.
I'm curious if this version still has this leak.
Just because it didn't get a new release in years doesn't mean it's somehow got worse.
Some software just works.
In short, none related to how people use Winamp: to play music files and streams.
