I’ve also heard that there is a special service for such problems that works with your GSM cell phone. Dial a certain number and hold your phone in front of the speaker for about a half min., afterwards you’ll receive the song title and artist by SMS. Of course you have to pay a small fee. Canâ€™t find the number unfortunately, since Iâ€™ve only see the announcement on TV.
Pretty neat service from what I have heard, It has a hard time with electronic/underground/obscure tracks though as alot of them just aren’t in their database, but other than that I hear it works fairly well.
