is anyone else still using an old verison of Shazam? As in, before they started charging. I'm using 1.7.0 on an iPhone 4. It's been getting buggy on iOS4 so every time I tag a song and then go back to the tagged list, the app quits. If you had the version since it was free and upgrade, you are not limited to the 5 song limit like you are with the now free lite version, correct? You essentially upgrade to the paid version, right? Are there ads all over the new version? I like the old version because there are zero ads getting in the way. Just want to know what all's in the new version to see if I should finally break down and upgrade or leave it as is. thanks!
