sansa clip plus. its got a microsd slot. i dont wanna use my phone much for music, because i depend on it for more important stuff like phone calls
clip plus was like $20 so if i lose it, no biggie.
what you could do is pick up an old android phone from ebay, root it and put a jellybean rom on it and music. i got radio on mine too (FM), doesn't even need a data plan for that. and about 8 GBs of music too on microsd. you dont need to drop $200+ on an ipod touch, android phones nowadays are comparable to crapple. put that shit on airplane mode and you're set. great battery life too. unless you want everything done for you, i suggest my method.
