like greg said, knowing the songs is barely half the battle. getting the so called " feel" is what takes time and experience.
Do this for all the genres of music you dont know.
Learn all the local radio stations that play:
DISCO
OLDIES
CLASSIC ROCK
80's
Listen to each station for 1 week. This week start with Disco and Oldies.
Do the same for all the other stations . Keep on doing this repeatedly.
Who cares if you dont like the music. Its like school, you may not like the subject but you need to take the class.
Keep on doing this until you get a good grasp of what is typically played for each genre.
At the same time, stay aware of all new stuff.
This should get you going.
Hope that helps.
Enjoy your stay and if you need any more help, there are a lot of wise and seasoned veterans on this forum. Just ask!
