Thousands. If you can play a I-IV-V and I-VI-IV-V you can get through most '50's rock'n'roll gigs without rehearsal. Folk can throw you some curves, as well as traditional country. You better know what you're doing for jazz, fusion or classical. Blues usually can be figured out with little trouble (unlike the lyrics would lead you to believe). After playing for close to forty five years I've had to learn a lot of material. Forgotten a lot of the "flavor of the month" hits but remember my favorite songs. To make a list at this point would serve no useful purpose.
