I am currently debating this for the near future. Here are the options I have come up with so far:
1. Buy CD's and play in car CD player
2. Buy CD's, rip to MP3/WMA, etc. and play in car CD player
3. Buy iPod, songs from iTunes, some kind of adapter (FM wireless/wired, Bluetooth, direct wired connection) to link to and play on car stereo
4. Buy other MP3 player, songs from other store, same adapter as in #3
I am not really interested in listening to music outside my car mainly because I am either in work, watching a movie or playing games. Buying CD's seems to be the least painful method as I am free to rip as I choose but then I am stuck sometimes with songs on a CD that I don't want. The iPod seems like a good idea also as I can choose songs that I want but connecting to a car stereo takes some work. Any suggestions or comments are welcome.
