My cheap Android tablet died tonight while listening to XLR8. Rather than make a late night run to Wal-Mart, I decided to see if there was a way to run Shazam on a Windows PC. After a bit of searching, I found an Android emulator for Windows called BlueStacks App Player. Downloaded and installed it, logged into the Play Store with my Google account, and installed the Shazam app. Everything worked perfectly and I was able to ID most of the obscure music that XLR8 played tonight.
Although I have only used it to run Shazam, the BlueStacks web site claims that it will run 96% of the Android apps out there. YMMV.
