Noticed this little nugget in the latest Chrome for Android update:|
4. Audio now continues to play while Chrome is in the background
Very handy indeed. Now it means I can play music from sites like Bandcamp, Soundcloud, Reverbnation (although I hate that site) and it will continue playing in the background when I switch to Kindle/Games or even locking the screen. Very handy indeed!
Not sure whether this works in the other Android browsers but I use Chrome exclusively so it is great for me. Hopefully useful to someone else here as well.
* For some reason it does not work with Youtube yet which is annoying. Will play around and see what is happening there.
