suddenly after 4 months I can't tag any music on the shazam app on I phone 3g only into it's 5th month of new usage.Does anyone know of changes to shazam use as,being disabled & having to disconnect my PC for now my I phone is my only source if music enjoyment & Shazam has Bern a favourite personal use app.Now I jeep getting error messages & told to log into support at Shazam which I have done to no avail.Very disappointing when trying to get info & link to music played on radio,tv,etc.Dies anyone else have this problem?
