Tried doing search here and Google for answers but turned into a wild goose chase getting me nowhere. Lot of similar threads but no answers for me. MacBook Air 10.7.2 with latest iTunes 10.5.3 and iPad (gen1) has 5.0.1 with Apple "Music" app that replaced their "iPod" app. Because of that ridiculous common problem of "iPad synced with another iTunes library", it won't let me move any iTunes songs which I imported from CDs, to my iPad unless I "erase this iPad" as that above message also says. This iPad was synced with an old laptop I no longer have but since there is a work-around to sync, is there also a work-around to transfer songs? In the "Sync Music" window on MacBook, I selected songs in iTunes to transfer to iPad but when clicking Apply I get that error as above. I also tried right clicking iPad in iTunes but there isn't anything applicable there to use, tried some anyway but nothing works. This is crazy. Thanks much for help with this!
