Remember analog cassette tapes? For those of you who remember spending hours making a super-cool 'mix-tape' for it to unexpectedly get chewed up by your boombox, then be prepared for a retrospective new gadget.

ThinkGeek.com has a Cassette MP3 Player that is actually playable as a regular cassette. If you've got a vintage tape player in storage, or maybe still in your car then all you'll need to do is purchase an SD or MMC card (2 Gb maximum) along with the Cassette MP3 player. The device is compatible with the MP3 format and supports bitrates of 32 - 256 Kbps.

This new retro device also functions as a standalone MP3 player so you can carry it around just like an iPod and listen to your digital music with the supplied earphones. The unit has a built-in lithium battery that is rechargeable via USB. The Cassette MP3 Player is available from ThinkGeek.com priced at $39.99
